Color Background
Tutorial requested by 
jadedsunset. Hope this helps and I hope I explained things well, it's been a long time since I wrote a tutorial.
Going from this:
to 
in Photoshop.
Level: Intermediate. You must know where to find the tools mentioned.
Translatable: The coloring no but the concept of creating the effect yes
1. First, you take your image and color it however you want. My personal style is bright and crisp, I don't like to over do it with color. To save time, I used THIS COLORING byl0vemetender.
2. MERGE ALL LAYERS (Flatten Image) and then DUPLICATE the image. This isn't necessary but I like to do it in case I mess up or want to compare it to the original.
3. Now we need to erase the background. It doesn't have to be perfect. You can use masks, which is what I prefer and there's a fantastic tutorial about how to use masks to blend images OVER HERE and it works for erasing backgrounds (skip to step 3). It makes it easier to correct any mistakes you may make while erasing.
4. Add Layer Mask, select a rounded paint brush and set it like so: Size: 110, Hardness: 50, Opacity: 100 BEFORE you begin brushing over the unwanted parts of the image, be sure the mask layer is selected or you will end up painting on the actual image instead of using the mask. If you brush over the unwanted parts and they don't erase, make sure that the color selected for your paint brush is black and not white. Black = Erase Image; White = Undo any erased areas
Tip: As you get closer to your subject (face, arms ect) you can lower the Opacity to 75% and the Hardness to 10 to give it a lighter, feathery effect.
5. Create a NEW LAYER and floodfill with the color of your choice. I chose a soft pink (#fad5d5) and set it to SOFT LIGHT, OPACITY 100% And you're done!
Extra Tips:
Alternative to Step 4: I suggested you use a round brush to erase the background and that's fine for a beginner, but as you get used to it, you may want to try the fuzzy brushes available out there to give a softer look. One such brush is THIS ONE by Annika von Holdt.
Alternative to Step 5: If after you set your color layer to SOFT LIGHT, the overall image is too light, you can add a Grey (#c0c0c0) COLOR BURN Layer AFTER the color layer. Play with the Opacity to suit your needs.
Alternative Result (Step 5): If you want to have the image the same color as the background, then simply set the color layer to COLOR instead of Soft Light and you got it!
