I just wanted to see if anyone has found for example the perfect ratios to make a bright purple . .
Well,
bright purples (or reds, etc.) are problematic if the mix is not started with a
very clear (untoned-down) purple.
The same is true for all other "bright" colors because most brands** of polymer clay have colors which have already been mixed with other colors at the factory... and those can't be "removed" later.
For example, a "tone" or a "shade" of purple
can be mixed starting from a clear purple, but a clear purple can't be mixed from a tone or shade of purple.
("tones" contain a bit of brown or several colors that make brown, or they contain the complement of the color they're added to ... "shades" contain a bit of black... and "tints" contain white)
**however, Kato Polyclay has 8 clear "spectral" colors, and Premo has two sets of primary colors which are "pure" but either on the warm side or the cool side of that color (so those clays/brands will often give the most
possibilities for mixes of all the colors that are closer to pure colors or "bright" colors --other brands may also have good clear versions of
certain of their colors as well)
One trick for brightening whatever color you have though is to mix in some
fluorescent clay of a similar color.
Pinata alcohol inks and pure-color artists' oil paints can be mixed in too to try and get any color closer and closer to the pure color too (but
Adirondack brand alcohol inks can't be used in the same way because their colors are all already toned down at the factory).
. . . or a this or a that etc. . .
Recipes for various kinds of purple as well as all kinds of "this and that" colors, can be found on the page I mentioned before though if you want lots of suggestions or just places to start for a mix:
http://www.glassattic.com/polymer/color.htm(for purples, or other individual colors, check
Recipes & Combos >
Individual Colors)
The category at that same page on mixing your own complete "
palettes" of color can also create lots of purples, but they won't necessarily be discussed separately.
Actually, the link I posted in my last message went to the "other" part of the color topic I'd posted, and it didn't have the samples I was thinking of... here's the right link:

different than all the others in the pic --they look similar just because of the limitations of internet/monitors/etc.):
