How would I recolor a blob?

[SakuraMagic]

So I made a blob.

It has different shades of the same colour (green).

I want to change all the shading to blue (with blue shadings).

How would I do that?

I used to know from a tutorial, but I think it was for a different program.

I just need to change the green shading and colour in blue shading and colour.

Is there I tool I could use?

Or do I have to recolour it all over again?

Adjustments > Hue/Saturation

The hue slider changes the colour.

Tanel made a plugin called Hue/Saturation IMPROVED which works a *lot* better than the built in one. Just download the ZIP (near the top) and move the DLL into your 'effects' folder.
