There seem to be several coloring schemes for tones. 黑紅紫綠 is the one I learned. 
I was in Qinghai a few years ago having an expensive coffee when the laoban wished me a DWJKL. I asked where I could see the races. He said they didn’t have any.
TOP (Tonally Orthographic Pinyin) uses the scheme illustrated in my post.
These are mnemonics for younger learners: blue is high like the sky (tone 1); green grows up, like a plant (tone 2) black is low like dirt (tone 3) and red is a falling tone like you’re angry (tone 4.) Neutral tone is gray. Everything is chosen deliberately to try to reinforce the contour of the tone, and since learners of Mandarin don’t come into the language knowing the tones for the color words, that scheme is only really useful (mnemonically speaking, I mean) for those who know the colors (correctly).
There is a free converter (Pinyin with tone numbers to colored TOP for web or text) at http://www.chinesepronto.com/triple/flashfix.php.

By the way, why is there a pinyinizer in this forum, but no “tone numbers to tone marks” converter?
These tone numbers are so extremely ugly to read.
Please use tone marks, guys!
Um, I think the mods are on top of that sort of thing, actually. Thanks for your concern.
