I've browsed around and can't find what I'm looking for. I am experienced in Photoshop and Illustrator both to a certain degree, but would prefer something in Illustrator (scaling vector image).
How do you go about designing and creating such a smooth gradient as in the following image? Are there any tools or methods for helping with color selection? Also, the subtle "blocking" or "sectioning" throughout where there a little slice of similar, but different colors? Just looking for an overall methodology in the design and creation of these commonly popular designs.
Bonus: Anyone seen any HTML5- or CSS-only implementations?
Thanks as always, geniuses!
