RGB

c = RGB (r, g, b)

Returns the RGB color code for the specified color values. r, g and b are the three color channels red, green and blue and take integer values from 0 to 255 for each of the color. Values outside that range will be clamped. The return value is a negative 24bit value to be used by the drawing functions.

Example 1

c = rgb(12, 123, 240)
rect 10, 10,  50, 50 color c filled
rect 60, 10, 100, 50 color rgb(212,123,240) filled

Example 2: Clamping of values

c1 = rgb(-12, 1023, 240.4)    ' same as rgb(0, 255, 240)
c2 = rgb(0, 255, 240)
rect 10, 10,  50, 50 color c1 filled
rect 60, 10, 100, 50 color c2 filled

Example 3: Fading colors

Def txt(t) = "     " + t + "     "
For c = 0 to 255
    Color 15, Rgb(c,     0,   0): At 10,   0: Print txt("1. RED");
    Color 15, Rgb(0,     c,   0): At 10,  30: Print txt("2. GREEN");
    Color 15, Rgb(0,     0,   c): At 10,  60: Print txt("3. BLUE");
    Color 15, Rgb(0,     c,   c): At 10,  90: Print txt("4. CYAN");
    Color 15, Rgb(c,     c,   0): At 10, 120: Print txt("5. YELLOW");
    Color 15, Rgb(c,     0,   c): At 10, 150: Print txt("6. MAGENTA");
    Color 15, Rgb(c,     c,   c): At 10, 180: Print txt("7. GRAY");
    Color 15, Rgb(c,   c\2,   0): At 10, 210: Print txt("8. ORANGE");
    Color 15, Rgb(c\2, c\2,   0): At 10, 240: Print txt("9. OLIVE");
    Color 15, Rgb(c\2, c\4,   0): At 10, 270: Print txt("A. BROWN");
    Color 15, Rgb(c,     0, c\2): At 10, 300: Print txt("B. PINK");
    Color 15, Rgb(0,     0, c\3): At 10, 330: Print txt("C. NAVY");
    Color 15, Rgb(c\3, c\2,   c): At 10, 360: Print txt("D. SKY");
