STEP ONE
Crop your image 100x100. If you need to, add a screen layer. I did not have to. Do whatever else you do before colouring an icon.
STEP TWO
Goto Image > Adjustments > Selective Color > Blacks > 100
STEP THREE
Add a new color fill layer (Layer > New Fill Layer) with this color #0b042b. Set this layer to Exclusion @ 100%
STEP FOUR
Add a new Selective Color layer with the following settings
REDS: -100, 100, 100, 100
YELLOWS: -100, 0, 100, 0
NEUTRALS: 65, -20, -50, -15
