Set a layer above it with the preffered colour, set the layer to clip, and the blending mode to multiply.
Clip will use the underlying tileset's alpha(so it won't work if you use255,0,255 pink), and multiply will mix the colour with the tile as the game does.
Quick question, when you say set the layer to clip you mean the colored layer with the multiply blending right? and i create this clip by doing layer => create clipping mask?
When you say alpha you mean transparencies right? like if certain portions of the image is see through? I see people referring to alpha layers around here, is that just another layer where you draw with transparency in mind, like if I wanted the background color to show through a window, I would draw the window panes on another layer and make them transparent.
And pink is basically the equivalent of transparencies right?
Also Should i set a background color? and if so which color does the game usually use. or is that something I get to choose in the raws.
thanks for the help
