Color on a screen will vary from situation to situation, being affected by such variables as browser, screen color depth, operating system, age of a monitor, settings for a monitor. The following color charts are the so-called Web-safe palette that shows similar colors on a PC Windows screen and an Apple Macintosh screen when the screen color depth is set to 256 (8-bit) colors. Other situations will vary, especially the thousands settings (16-bit) color setting.
HTML colors are hexadecimal numbers composed of three duples, one duple each for the Red, Green, and Blue components of emitted light: rrggbb
Colors here are constructed using the duples of:
- 00 (no light emitted)
- 33 (some light emitted)
- 66 (moderate light emitted)
- 99 (much light emitted)
- CC (very much light emitted)
- FF (maximum light emitted)
Below, the colors are presented in tables using table cells with colored backgrounds (
bgcolor="#rrggbb"). Rows represent Red, and columns represent Blue. In each table, the Green component is increased from the previous table, and the green component remains the same for the table. Together, the tables represent layers of a cube of 216 colors.
Notice that the middle groups, with medium amounts of green, tend to be the most interesting colors; they are more complex than colors with extreme amounts of one or the other colors.
The darker first rows may appear to be the same, but they are not!
