Changing Layer Colors En Masse

[cohans]

I have a layer with a globe image containing various shades of blue and white. I've placed this over a background that is more of a wedgewood blue series of colors.

The blues of the globe don't look good with the wedgewood blues of the background.

How do I alter the colors of the globe en masse to find colors that look better with the wedgewood blues?

I use Photoshop 7 and I'm more towards the novice/internediate side of the spectrum.

Thanks.

create a hue/saturation adjustment layer. Then clip this layer to your globe layer (with the hue/sat adjustment layer selected and placed above the globe layer [which it should be by default] go to layer - create clip mask). Now slide the bars until it looks good.

Does that make sense?
