Cool Background Image: Colorful Spectrum Nimbus WordPress Themes

A cool, colorful spectrum against a dark background–free to you, for use in personal and commercial work.

By Ars Grafik

On the eve of this new year, we thought it would be appropriate to share a festive, cool background image of a colorful spectrum. The spectrum background was created in Photoshop using the noise, motion, and box blur filters, with some gradient overlays and blending applied as well. It’s a pretty cool effect for a background image. The background would look great in photo manipulations, on its own in web pages, and anything else you can think of. The file is a .png (was produced in 16-bit color) and is 1248 x 1200 pixels.
