How is the color value specified in the database table?

Answer: Each color has a designated RGB value. The integer value (long) may be calculated for the color parameter, then specified in the database table, through the following formula:

• Color parameter = R + G * 256 + B * 256²
  
  where R, G, and B may be 0 - 255

For example, blue has a RGB value of (0, 0, 255), therefore its color parameter is 0 + 0 * 256 + 255 * 256² = 16711680.
