About Working with text descriptors (tags)

Question

Hi, I see the Text Tracks tutorial for QT Pro, so I decide to make some subtitles for a video and change the color of the text, but the tuto say about RGB colors an the numbers that fills are 5 digits. But I learned that RGB only uses a scale of 0-255 to fill all the colors, So how can i get the most common colors or is there an algorithm or some kind of these to obtain other colors like say pinkish, redish or greenish??
I only want a yellow color for the subtitles, but I've interested on the way to obtain more colors, so if anybody knows, please tell me. I really appreciate it!!

Yep. Very confusing and you need a calculator to figure them out.

But someone did it for us.
I wish Apple would put the "Color Wheel" (version 6) and some of these other options back into version 7.

One of my "movies" that uses the text track feature found in QuickTime Pro.
And, I used a "yellow" color for the text track.
