There's this misconception floating around that space is gray, and the colors shown in space images are all fake. Completely not true. It comes from a combined misunderstanding regarding how our eyes work, and how cameras work. Monochrome cameras are used to capture these images, yes, but by cycling through filters they accurately capture the true colors of the objects, the same as any point-and-shoot digitial camera. They are captured this way because it allows for the camera to capture more unfiltered light in less time, which is important when the object is faint, like this are.
What does that have to do with this image? I threw my real color data away and hand painted it, something that is never done by astrophotographers. It was more of a fun project than anything else to have fun with some wild colors. To see what the true color looks like, check out the attached image!
