I have a new feature that is in the early stages of development. It is an art media color table and brand application. It is not complete and doesn't have all the info it will eventually have but it is starting to be usable. Right now, sorting by color name in the default page shows the differences between different vendors names for a color. You can also search for all color samples with a particular word in their name.
You can try it out at:

• ColorChart Chart of color samples
• ColorBrand List of brands with data being entered

Over time, I will also enter data for RGB values and allow sorting or grouping by color and color groups and perhaps allow for reviews of brands.
I plan to add more brands over time but will restrict it to those brands considered artist grade. I will take suggestions but it could be quite some time before I can get to adding them since I still have a lot to do with what I am working with.
