[TxMt] web color palates for TM?

Hi everyone, Great discussion about the icons (though I agree it's perhaps the least important aspect of TM). During a bout of insomnia I fancifully thought up one that would just be "\B", as in "escaping BBEdit" :)

More seriously, I found myself opening BBEdit yesterday just for the web color palate. Does anyone know of a similar swatch picker (perhaps standalone) that would work within TM? Generally I use only a few colors, but I'm color-coding cell backgrounds based on numeric scales and need to see the whole "spectrum" as it were to help choose them.

Thanks for any tips...

Paul
