How To Add Color To A Black & White Image With A Layer Mask/Photoshop Layers Explained

A Beginner’s Tutorial On How To Use Photoshop Layers, Layer Masks, And Bring Back Color To A Black And White Image (All-In-One!) With Image/Screenshot Examples
*Note:  This article might look long/hard but it’s because it’s written assuming you know nothing about how to use Photoshop so it’s just very thorough.. this is VERY easy and fast to do!

Many years ago my husband got Photoshop for me.  I was super excited.. I opened it up and was so overwhelmed I didn’t open it up again for another year!!!!  WHen I did open it up a year later, it was because I had seen an image on Facebook and someone noted on it “Edited with auto color in Photoshop”.  “Auto edit????  I can do that!”.  And I excitedly opened it back up.  Once it was re-opened I started playing around with it more and learning new things about it.  I was still very confused about how you could add color to a black and white image and my husband explained it like this: Imagine you have 2 photographs.. a color photograph, and a black and white version of the exact same photograph.  Imagine you put the black and white photograph on top of the color photograph and then take an eraser and erase away parts of the black and white image to reveal the color beneath it.  ta-da!  Like magic, I now understood the concept of Photoshop layering! The very first thing I learned how to do with layers was add a pop of color to a black and white image.  You can do it as I stated above (layer a bw image on top of a color image and use the eraser tool to erase away the bw image to reveal color) but the issue with doing it that way is.. what if you make a mistake?  What if you erase away too much?  You cannot go back to add the black and white back.  For that reason I want to teach everyone how to use a layer mask.  With a layer mask (VERY easy to do!!!!) you can remove parts of the top layer AND bring them back again!  And you can use it for endless different projects beyond a selective coloring/color pop image! I’m a very visual learner so that’s how I like to explain things as well.

^STEP ONE:  Open The Image
We’ll start with what your image looks like when you open it in Photoshop:

^STEP 2:  Duplicate Layer
This is the step where you layer 2 images on top of one another.. do do this by going to the layers palette, right click on your layer, and select “duplicate layer”.  You can also simply go to your menu on top of the screen and click “Layer>New>Layer From Background”.

^STEP 3:  Turn The Top Layer Black And White
Make sure your top layer is highlighted in the layers palette and then turn your image black and white :).  You now have a black and white image on top, and a color image on bottom.

^STEP 4:  Add A Layer Mask
This is where you add the layer mask I was mentioning earlier.. this mask will allow you to remove parts of the black and white image as well as bring back parts of the black and white image.

^STEP 5:  Select A Black Paintbrush
Your layers palette should now look like this.. the white box next to your bw image is the layer mask.  You will use the black paintbrush to remove the black and white image, and the white paintbrush to bring back the black and white image.

^STEP 6:  Verify Your Layer Mask Is Selected
If you have anything other than the layer mask selected, this will not work and the paintbrush will work normally (adding a white or black streak on the image).

^STEP 7:  Paint Anywhere You’d Like To Add Color Take your paintbrush and paint anywhere you’d like to add color!  It’s that easy!  If you run over the lines, it’s okay.. you can turn it back to black and white which we address in the next step.

STEP 8:  Select The White Paintbrush To Bring Back The Black And White Image
Change the color of your paintbrush to white and paint over anywhere you did not want to bring the color back.  It helps to scroll in very close to the image, use a brush that isn’t 100% soft, and make the edges as clean as possible.  It looks very sloppy when the color runs outside the lines.

^The image after cleaning it up with the white paintbrush (again verify that your layer mask is clicked on!).

^STEP 9:  (Optional Step):  Reduce The Opacity/Strength Of The Colors
I always feel that bringing back the full strength of color in an image is just too intense/harsh.  For this reason I like to make it sort of a blend of half black and white/half color.. this tones down the coloring a lot and makes it look much more gentle and blends better.  (This is just my opinion and what you like may be different!  I compare a full strength color pop image to a partial strength color pop image here if you’d like to compare for yourself).

^This is the image with the coloring reduced by 50%.. it blends much better.

I’d like to make a quite note that the above images are not ones that I would choose to do.. They are only edited this way for the purposes of this article.  If I brought back color to anything I would choose the boots but for the purposes of this article I wanted to choose something that was easy to see and overall I just prefer this photo in color :).

I really hope this helps you all learn some more about how to use layers in Photoshop and how to add color to a black and white image!

1 Tip Which Will Improve Your Color Pop/Selective Color Images

I frequent many photography forums and one topic that comes up often is “color selection” or “color pop” edits.  This is when you have a black and white images and you bring back color on just a couple select spots.  These images are not often well received by lot of pros.  I am amongst this group 🙂 but they do have their place :).
I think the worst part about color selection is just how harsh the color is in the image.  It doesn’t flow well.  This is when I created my own way of doing color selection photos, where you just bring back about half of the color instead of all the color.  It makes a huge difference!  And I definitely much prefer the subtle color to the sharp, vivid color.

How do you accomplish this?  If you are layering a color image over a black and white image and erasing, then erase away at around 30-40% opacity.
If you are using a layer mask, set your paintbrush to around 30-40% opacity.  tada!  Very simple indeed.  This will make a huge difference in how the photo looks after you edit it.

One other tip I have is to pick just one focal point to selective color..a lot of people go a little crazy with their brush and bring back half the image so it’s half color and half black and white.  This looks a bit odd and unnatural and also there is no real concept behind it.  Usually you want to color pop something with meaning or symbolism or a concept (not always but like usually just an item vs a shirt).  In the sample image I am posting here I decided to have 2 color pops so they would balance each other out more but notice the items I picked were small so it doesn’t overwhelm the photo.  I believe my opacity for this image was around 30%.. to do it again I  might bump it up a bit higher, but you get the idea.

This is the image at 100% opacity.. this is the full color image brought back to the black and white image, and this is what most photographers who do color pop do:

^ Color brought back at full strength.

And the photo shown below is the same image with the color brought back around 30% opacity.  It might even be more like 20%. It is a little bit dull but it looks so much less distracting and more natural.. I much prefer it to the full color photo.

^Color brought back around 20-30% strength.

For one more example I’ll show one brought back around 50% opacity.

^Color brought back around 50% strength. This is my favorite edit of the three (I might tone it down a notch but overall the color isn’t too overbearing and “sharp” and it blends much better than at full strength – in my opinion anyway!).

As with all things in photography, which is better is subjective.  Surely there are people who prefer the first to the second.  If you do like the first you could even play around with bringing back the color around 70%-80% so it’s just not so vivid and contrasting.  While I’m not a huge fan of color pop photos, I do find myself much more receptive to them when done in a more subtle manner, just thought/style I would share with everyone :).
