## 4.8 Specifying colors in JpGraph

Colors can be specified in three different ways

1. By using one of the, roughly, 400 pre-defined color names, e.g
   `SetColor ("khaki");`

   A named color can also be modified by adding a adjustment factor. An adjustment factor, 0 < f < 1, a smaller value will give a darker version and a value of 0 or 1 will return the original color. A value > 1 will make the color brighter. A few examples

   `SetColor ("khaki:0.5" ); // A darker version of "khaki"
   SetColor("yellow:1.2"); // A slightly lighter version of "yellow"`

2. By specifying a RGB triple, e.g.
   `SetColor(array(65, 100,176));`

3. By specifying the color as a hex string value
   `SetColor ("#A16BFF");`
