Color codes for Bullseye glasses?

Postby samullin » Thu Mar 08, 2018 4:49 pm

Hello,

I searched the forum and couldn't find anything addressing this.

I was thinking about a project where I'd need to algorithmically match colors to the nearest Bullseye glass. I admittedly know nothing about color theory, but I do know that for this to work I'd need some type of color code defined for each Bullseye glass in the catalog (or at least some subset). Does such a thing exist? In principle, it looks like RGB, CMYK, pantone, or any other color system would, in principle, work for this purpose.

Any advice would be most appreciated.

I don't quite understand if you are are just looking for a color chart, or you need a coding system that indicates color mix, saturation & value. If you just want a color chart, it is provided in the catalog:

The colors are a bit subjective, e.g. what is difference between "Pea Pod Green" and Mint Green".
Computer color schemes don't really work, as computer colors are strictly subtractive, colors in the physical world are additive. So this it would be a bit difficult to do this with an algorithm. Even if you scanned all the BE glasses, this would be fairly unsatisfying. RGB allows for millions of colors. BE has 63(?) colors for all practical uses. * I'm not counting streaky,etc. glass since those are not one solid color.

I worked for an artist once and was building his website. He would sometime try to tweak it himself. He was really frustrated with the concept of subtractive color changes, after a half century of mixing/adding paints to each other. :lol:

I'm really curious - do you NEED to do this or was it just an idea? If need -for what purpose?

Even the additive potential of the glass is a bit limited for most, since the glass is granular and even when melted it doesn't just mix itself. And then we have the reactive colors issue with some colors and the chemicals used to get the colors. E.g. Egyptian Blue and French Vanilla aren't going to net you a creamy, lighter blue. :mrgreen:
