@SinsofMidnight:

Cool, I think you'll se it soon! I love doing experiments with rainbow colors, I have done so many rainbow coloured walls :)

@Hifsa:

I believe there is one. I'm sorry that I have no idea what it's called though --I've never used Photoshop before, so I'm afraid I have no frame of reference.

I look forward to seeing you try it ^^

@SinsofMidnight:

Ohh, I'll definitely try this^^ looks amazingg :D I use photoshop but I can bet that this kind of an option will definitely be available in it too :)

@Hifsa:

Exactly ^^ Then I used gimp's "I-Warp" feature to swirl the colors in a different way.

@SinsofMidnight:

So, you used a rainbow gradient, I presume?

@Hifsa:

I used a gradient fill layer and messed with it's composition a bit... I'm not sure if that explanation really tells you what I did, though, lol

I'm glad you like it! It was really fun to make, actually, and pretty simple for such a result.

Thank you for your kinds words!

Wow, I love the composition and the colours of this wallpaper! Have you used an action or something?
