SUBROUTINE SETCO (COLOR) C$ (Set Color) C$ Define the index of the color required for subsequent C$ plotting, where "COLOR" is an integer in the range 0..255, C$ as follows: C$ C$ Index Color (R G B) C$ ===== ===== ======= C$ 0 Black (0 0 0), or default for device C$ 1 Red (1 0 0) C$ 2 Green (0 1 0) C$ 3 Yellow (1 1 0) C$ 4 Blue (0 0 1) C$ 5 Magenta (1 0 1) C$ 6 Cyan (0 1 1) C$ 7 White (1 1 1), or complement of the default. C$ 8..255 Index into the device-dependent color table. C$ C$ Color indices 8..255 if selected must be predefined by a C$ call to SETCI (Set Color Index). The color index will be C$ ignored for those devices which do not provide color. C$ C$ Some devices specify color with the subtractive primaries C$ cyan, magenta, and yellow, rather than the additive C$ primaries, red, green, and blue. The relationship between C$ the two is simple: (C M Y) = (1 1 1) - (R G B). C$ C$ (09-Jan-1991)
