What speculating?
Just kidding. In all seriousness, in programming my lighting, I needed to match colors of Par Cans to the color wheels of other fixtures. I won't mention the fixtures here since they are of a different brand, so I don't want to anger the powers that be at ADJ.
But in all seriousness, as an audio guy, lighting is not something I really want to do, it's just something I have to do. So, how do you get pink from Red, Green and Blue?
Simple. I do HTML as well, and so I looked up values via web sites, and was able to get hex values, which of course go from 00 to FF, providing a full range of 256 variables. A quick converison using the Windows scientific calculator in the Accessories area, and I converted the hex values to decimal, used those values in the DMX Operator, and I got the color I wanted.
Easy.
There are multiple ways to specify colors in HTML, and knowing how to read them makes all the difference in cheating via this method.
There is the "insert color name here", but that is limited to a small group of colors. The better methods are the hex method, where you see things like "color="CCCCCC"(which is a grey) using hex values, with each 2 characters representing Red, Green and Blue respectively. Another method, that is not used as much anymore is the older decimal value, which would be more like color=204,204,204(which is the same as the hex above)
Since DMX values give you 0-255, and 2 hex characters give you the same amount of numbers, and decimal is easy, trust me, using gets that are the right color(pure red, pure green, pure blue) and proper focus and aiming, you can get the colors you want. And getting these gel sheets is a cheap and easy task. They are common colors in high demand and don't cost a whole lot to get.
As Jingles said, it is RGB mixing, which unless you're using traditional par cans and gels, you're doing anyways. Why not cheat as much as possible. Plenty of people are making life easier for everyone by publishing all sorts of information. It's your duty to look it up and use it. I figured this all out on my own to resolve my task, and I definately was thinking outside the box.
