 ==== Description ====
-Sets the current drawing color to //colorname// or to an ARGB value where ( (a * 256 + r) * 256 + b) * 256 + g.  If a single color is specified both the pen and the brush will be set to the same color.
+Sets the current drawing color to //colorname// or to an ARGB value where ((a * 256 + r) * 256 + g) * 256 + b.  If a single color is specified both the pen and the brush will be set to the same color.  There are 4 common ways to define a color in BASIC256:
+  - one of the defined color constants (see table below);
+  - an integer to define the color where ((a * 256 + r) * 256 + g) * 256 + b,
+    * a - transparency 0 = transparent to 255 = opaque
+    * r - red 0 = off to 255 = full on
+    * g - green 0 = off to 255 = full on
+    * b - blue 0 = off to 255 = full on
+  - the [[rgb|rgb]] function passing it 3 or 4 numbers from 0-255,
+  - or using an svg color definition string.
 When drawing solid shapes ([[Chord|Chord]],[[Circle|Circle]],[[Pie|Pie]],[[Poly|Poly]],[[Rect|Rect]], and [[Stamp|Stamp]]) the border of the shape will be drawn with the pen color and the shape itself will be filled with the brush color.  A brush color of CLEAR is used to not fill a closed shape.
