Hey guys,
I'm new to Photoshop and I want to try and do something pretty simple but I can't find the words to Google it properly. What I'm wanting to do is make a 16x16 greyscale tile and each grey pixel acts like a shade of colour, then I want to be able to pick a base colour and add it to a layer. Then ideally both layers merge together and create a coloured tile, being able to switch from one colour to another.

I hope the example picture above helps with the understanding.
Thanks from Cubies.
