Properly replacing a colour in a simple bitmap

[M4R5]

I have a low-res bitmap. It has a dark grey background with a plain white icon. The transitional pixels are various shades of grey.

I want to make the dark grey into a bright blue, leave the white white, and have the transitional pixels changed to maintain their respective "in between" values.

I do have Photoshop CS2 but I though Xara was more likely to be able to do this. Can anyone help?

Thanks

Xara Designer Pro X has a Color Select/Erase Tool that can do this, though to be honest, the results vary.

Aw I don't seem to have that tool in PGD6. Any other ways? Seems like this must be something people do all the time.

Thanks

Can we see the bitmap?

black and white is easy - to replace the white you give the bitmap a stained glass transparency put a colour rectangle behind select both and make a true colour bitmap copy

to replace black just invert the bitmap first
