An astronomical figure." If I may make a geeky correction: I'm pretty sure he was told 16.7 million colors (or the person who told him was originally told that). 16.7 (or 16,777,216 to be precise) is 2 to the 24th power, and is the number of possible colors most modern computer displays are capable of (ignoring hand-held things which often use cheaper displays). This so-called "24-bit color" is broken down into three 8-bit numbers (with values between 0-255) for red, green, and blue -- the primary colors of light, which combine together to make all the colors the human eye can see. (There are higher bit color images, but these contain either transparency values [a.k.a. "alpha"] or the increased color range is used to keep the image from being degraded during image processing. Most actual displays top out at 16.7m colors, and these are exceedingly common.) Also, there is way, way more than 16.7 million stars in the sky and 16.7 miles is only like a fifth of an AU, so "astronomical" is a tad of an overstatement. More like "an entirely mundane figure". I think maybe the projector salesman wasn't being entirely forthright. “I was told that it can make 16.1 million different colors. An astronomical figure.”
