Changing hair color is a technique most new digital editors would love
to do to their images. You know - brown to blond or red or
blue.
Amaze your friends and family and have a blast with it ...
The reality is that hair has all of those little strands and fiddly
bits that make it a very difficult thing to modify.
More advanced techniques use the Photoshop Channels to isolate the
strands and then apply a color change. This method is quite
effective.
An easier method is to work with selections, specifically the Quick
Mask to selected the hair and then add a Solid Color Fill Layer.
When all is said and done, the effectiveness of the selection
is the one thing that will determine the effectiveness of the hair
color change.
Of course, the Quick Mask selection will be best completed with a Wacom
Bamboo or Wacom Intuos ...
So maybe this is a tutorial on selections with the result being applied
to changing hair color ...

Quick
Mask
Photoshop's Quick Mask is one amazing selection tool. If
you're not familiar with the Quick Mask you can check out the Quick Mask Tutorial
or follow along here to get the basics as the apply to changing hair
color.
A quick refresher ...
The Quick Mask is called that because you are actually making a Mask on
an image.
Quick Mask Mode is entered by clicking on the little button (outlined
in red) at the bottom of the Photoshop toolbar or by pressing the "Q" key on the
keyboard.
Nothing much will change other than the foreground and
background colors will change to black and white.
To select an area in Quick Mask grab the paint brush tool and use your
Wacom pen to paint
black over the area you want to select. If you make a mistake
then switch to white and paint out the error.
If you want to have all of the little hair strands included in the
selection then zoom way in,
decrease the brush size down to a pixel or so and carefully paint over
the strands. The pen (Wacom Bamboo or Wacom Intuos) makes this so
much
easier
to accomplish.
When satisfied with the selection press "Q" again or click
the little
icon to the right of the little red square to leave Quick Mask.
This will produce a typical marching ant selection that is the basis of
changing hair color.
Here is the Mask that was created using Quick Mask on the sample image.
Other
Selection Methods
For those who are more comfortable with other methods of selections -
well - they can be used as well.
The Lasso tools will do an acceptable but not great job.
The
Pen Tool and a graphics tablet will do a fabulous job if you know how
to use it and have the
patience to work your way around the hair and little strands.
The advantage of the Pen Tool is that you can save the path
you
create, go away for a day or so and come back to work on it again.
If you want to give it a go then click the link to learn how to use the
Pen Tool.
Feathering
and The Fill Layer
After leaving Quick Mask Mode
the typical marching ants will appear with your selection.
At this point some Feathering can be added - go to Select > Feather,
change the amount and click OK.
Take
a close look at the selection and if any of the little strands have
disappeared from the selection undo the Feather and try again.
The next step is to change the color of the selection - thereby
changing the hair color.
This is accomplished by adding a new Fill Layer above the image.
Layer > New
Fill Layer > Solid Color
This will bring up the New Layer dialogue. At the bottom of
the dialogue is the Mode:
button - change the Blending Mode to Soft
Light and click
OK.
Now the fun part begins and that is actually changing the hair color in
your image ...
Changing
Hair Color
After clicking OK in the New Layer Dialogue the typical Color
Picker will come up - and this is where you select the new hair
color.
At this point you have unlimited color choices.
Move to Color Picker to one side of your monitor and mess around with
the sliders just to see what happens.
When you are in the Color Picker you can move the cursor off of the
palette onto the image and the cursor will change to the eye dropper.
If the eye dropper is used to sample a color on the image the
hair color will change.
How can you use this? Simple - sample a piece of clothing to
have the hair match (more or less) the clothing.
Samples
The top left is the original hair color and the rest are variations.
Fill
Layer Versatility
Up to this point we have been using a Solid Color Fill layer which
works quite nicely.
There are two additional modes in the Fill Layer
dialogue (Gradients and Patterns) and both of them can be used
to create some really unusual and interesting hair color changes.
The steps are exactly the same ...
make the selection
choose the type of
fill layer
change the Blend Mode to Soft Light and
select the
fill (either Gradient or Pattern).
Gradient Fill Layer
This is one of the Metal gradients. If she had this done by a
hairstylist it would probably be very expensive and time
consuming.
The settings are ...
Style: Reflected
Angle: 151.9
Scale 64%
Pattern
This is one of the Photoshop patterns called "Tie Dye".
The only setting available is Scale: and it's set to 932%
Further
Adjustments
Levels
It's always a good idea to check out the Histogram to see if it covers
the full range. If not then move the Black or White slider to
fill in the full range.
If you find some color leaking into parts of the image where it
shouldn't be just grab the eraser and remove the offending color cast.
It's best to use a large, soft edge eraser to prevent hard
edges where the erasing was completed.
There you have it - a fairly easy and straightforward method to change
hair color.
Give the different Fill Layers a try and prepare to amaze yourself!
CS5
Photoshop CS5 takes some adjustments to a whole new level and that
includes a hair color change. Depending on the complexity of the
hair, using this method can be quick and painless or quite challenging.
If the Mask Panel is new to you then perhaps it would be useful to
watch the 3 videos on the Mask page.
The new Masks Panel in CS5 makes it much, much easier to modify a
selection with the Refine Mask adjustment. It may seem a bit
strange at first but once you become familiar with it then the Masks
Panel will become part of your normal Photoshop workflow.
The goal here is to completely select all of the hair including the
little strands and that particular project can be very, very difficult
and frustrating. Once selected it's a simple matter to add a Hue
and Saturation layer to color the hair.
Here is the image we'll work with in CS5 ...
This is a more difficult one to work with because of the little fiddly
bits of hair over and above her shoulders.
The first thing that doing is to make a copy of the Background Layer
because we are going to be adding a Layer Mask and you can't put one of
the Background.
Activate the Copy of the Background and then the starting point is
exactly the same as before - with a great selection using the Quick
Mask brush or perhaps the Lasso Tool. In fact, it really doesn't
need to be totally 100% perfect because the Refine Mask adjustment will
take care of a lot of the left over problems.
Quick
Mask Selection
Lasso
Tool Selection
I tried both selection methods and had the best results with the Lasso
Tool and that's probably because I was using my Intuos4 to make the
selection.
Now add a Mask to the top layer and then click on the Mask panel.
Part way down the panel is the Mask Edge ... button.
Click on it and now you've got a whole lot more options to refine the
mask (which is the hair).
This is the Refine Mask panel and there are lots of options.
You can view your mask in 7 different ways.
When Show Radius is selected and the Radius slider is moved up
(generally quite a lot, by the way), you will see the edge of the mask.
To the left is the Refine Mask Brush. This is where you take your
Bamboo or Intuos pen and paint in the radius to improve the mask.
Shift Edge (the bottom slider in the Adjust Edge panel) will increase
or decrease the selection.
Color contamination in the mask can be eliminated or modified by
checking Decontaminate Colors in the Output panel.
It may be necessary to fiddle around in this panel for awhile to get
the mask right.
You can always click OK, add a Hue and Saturation layer to check the
results. If they are not what you want then open the panel and
start again or go back in the History Panel just before the Mask was
made.
Here is the photograph with the hair color changed to blue-purple ...
If you're even more adventurous how about adding a Gradient Adjustment
layer? This is how the image looks now ...
This is one of the Color Harmonies 1 gradients at 100% in a Diamond
Pattern reversed. It's kinda neat.
Remember - if the Mask Panel is a bit confusing then check out the
videos on the Mask Page.
