Changing image color

Question

I have an image of a gradient. It's in a dull grey, and I would like to shift the enter thing to a bluer color without changing any of its other properties.

What's an easy way to do this?

I have both photoshop and gimp.

Thanks.

Answer 1

Photoshop: The Hue/Saturation adjustment tool (shortcut Ctrl+U at least in PSCS3, accessible via Image > Adjustments > Hue/Saturation otherwise) has the "Colorize" option, which preserves the lightness of the color, but changes the hue and saturation values to any given color.

Answer 2

The Colorize-Option should work for this pretty well.

Answer 3

Even though you didn't specifically ask for it in the question, I thought I'd post how to do this in Paint.NET in case anyone is looking for it.

I was able to simulate Photoshop's Colorize feature by doing to following:

1. Open your image file
2. Add a new layer above the gradient
3. Set the Opacity of the new layer to something low like 30
4. Use the rectangle tool to draw a solid blue rectangle across the whole image

If it's too light or dark, you can adjust the transparency of the layer OR use a darker/lighter blue.
