How to Understand Color Codes

"Here's a download link for the program which also includes the source code. Note that the program is colorcoder.jar. The program has been designed so you can use it whenever and wherever you need it. It should run on just about any operating system and doesn't need to be installed on a computer (although it does require that a reasonably up-to-date version of Java be installed.) You can even run it off a USB memory stick if necessary. When run, the program will check to see if it has permission to write a tiny (0.15 KB) history file in the same folder that the program is housed. If it has permission, it will use this file to record any colors that you've told it to store in the palette. If it doesn't have permission to write the file the program will work normally, but color samples stored in the palette will be lost once the program is closed.

"Color Mixing

"As a child, you probably recall learning that white light is actually a mixture of many colors. The same principle also applies to color codes. When trying to create the color you want with color codes, you have three base colors (red, green and blue) which you must mix together to create the final color you want to display. Instead of simply thinking of them as just colors, think of them as colored lights where you can increase and decrease the brightness. If you look at the color mixing bars in the left side of the Colourcoder window you'll notice I named them lights to reinforce this idea."
