For colorize use adjustment layers, which are located on the left of the "Create a new layer" icon in layers pallete. My favorites are Hue/saturation, Color balance, Channel mixer. Play with them and you`ll see the advantages of every one of them. The great thing about adjustment layers is you can edit them any time and they are not memory expencive :) Btw you can also copy the alpha channel from second document and paste it in the adjustment layer mask, which is the the white box linked to the adjustment layer. Click on it to make it active and press CTRL+V to paste the alpha channel :) Tihomir
