The c subroutine changes the current RGBA (red, green, blue, alpha) color. Array components 0, 1, 2, and 3 are red, green, blue, and alpha, respectively. In the three-component cases, alpha defaults to 1.0 (float) or 255 (integer).
Floating-point components range from 0.0 through 1.0. Integer components range from 0 through 255.
Note: This subroutine is available only in RGB mode.
| vector | Specifies, for the c4 subroutines, a four-element array containing RGBA (red, green, blue, and alpha) values. For c3 subroutines, a three-element array containing RGB values. |
| Array components 0, 1, 2, and 3 are red, green, blue, and alpha respectively. Floating point RGBA values range from 0.0 through 1.0. Integer RGBA values range from 0 through 255. |
The example C language program cylinder1.c calls the c3f subroutine, with a three element array initialized with all zeros as the vector parameter, to clear the screen to black.
