A long-outstanding request for ThrustCurve.org is to search by propellant color. If this is something you would like to see, could you please answer a couple of questions:
1. Would you expect every propellant to have a color?
My guess is that people would search for motors that have an "effect" smoke and/or flame when searching by color, so most motors would have no special value for color.
2. What "color" would you say for black powder motors?
3. Is it really "color"?
Motors can emit smoke in black or white as well as have a colored flame. We already have an indication of sparky motors (because their use is restricted).
To make the discussion more concrete, I've put together a page that lists all the propellant types by manufacturer. Right now the "Color" column just picks a color word out of the propellant name, but clearly we'd need some manual input since not all names include the color.

If searching by propellant color is a feature you want, please think of how you would categorize the propellants from your favorite manufacturer and consider what you would expect to get as a response when you did search for a specific color.
