Colour replacement tool problems!

[misty_moo]

Hi there - I would really appreciate your help!!
I know that the colour replacement tool is dependent on the brightness and colour of the source, but I really need to change a large portion of the cream building on this image to a darkish green colour. It is only for a rough mock-up so it doesn't have to be perfect, but I need to give my director an idea of what paint choices to make...
Any tips would be much appreciated!
Thanks a lot x

Re: Colour replacement tool problems!

Mask out the appropriate area. Create a channel mixer layer. Adjust to something close to the right balance, being careful not to over-saturate the color relative to the rest of the image. Use additional layers to bring back some of the lighting and shadow variation as necessary.

Keep in mind you need to consider how a darkish green building would appear under this lighting. Otherwise you'll end up with something that looks weird.
