The B NO 32 baby signal, according to the Price Guide, comes in the following colors:
Blue, Blue Aqua, Aqua, Green, Dark Yellow Green, Olive Green, and Olive Amber
The picture above is missing the aqua (I have one, just couldn't get it to fit in the lineup!), but MIGHT be considered to show all the other colors (in the same order). I'm never entirely sure about what color is what, and I'm sure it's open to interpretation. If you feel these aren't the right color names, I'd be interested in hearing what you think!
