The multicolored splash of hues isn't wrong. It's just an intense, particular personality that has to be used in a suitable place. I find that look frequently confusing and unfocused, sometimes cheap, but that's often because it's just irrelevant to the purpose of the page/niche. For example, if it's a niche about maybe bubbly twinks, a range of colors may? be more appropriate, or two candy colors. If it's goth twinks, that might not work. The point is the color and the intention of the work/tour/webpage have to be tightly aligned.

One way to find good colors, not saying this is foolproof, is to think of color by itself as your only way to communicate the ideas you want. What colors say the name of your site, the niche, and what you're selling, without having to use words or effects? The closer you come to that, the closer the whole design will be cohesive and focused.
