Ever wondered why anime forum sites get a lot of loyal users? Design may play a huge factor. I really liked how a particular website called solia Online played with colors.
Observing its header, it can be seen that the drawings are good. However, what I noticed is the intelligent use of color gradients. See how the color purple radiates into white and pink while it fades to bluish purple and how the brown clothes of the skin color of the character complements the background.
I also like the overlapping images below. Look at how the blue and red contrasts each other. Their artist may have known her colors quite well.
I think out of all the images in avatar forum websites, Solia Online is the most visually appealing so far.
