Convert hue, saturation, and value to composite color format
PgColor_t PgHSV( unsigned H, int S, int V );
ph
This function converts hue, saturation, and value into a PgColor_t structure.
A color circle is divided into 65536 gradations (called binary gradations or bi-grads). Hue is in bi-grads, starting with red at 0 (0 degrees), green at 0x5555 (120 degrees), and blue at 0xAAAA (240 degrees):
| Hue | Color |
|---|---|
| 0x0000 | Red |
| 0x2AAA | Yellow |
| 0x5555 | Green |
| 0x8000 | Cyan |
| 0xAAAA | Blue |
| 0xD555 | Magenta |
| 0xFFFF | Almost red |
The values for saturation and value range from 0 to 255:
| Saturation | Effect |
|---|---|
| 0 | Gray |
| 128 | Muted |
| 255 | Pure color |
| Value | Effect |
|---|---|
| 0 | Black |
| 128 | Dark |
| 255 | Full brightness |
A composite color value.
| Color | HSV value |
|---|---|
| Black | PgHSV( 0, 0, 0 ); |
| White | PgHSV( 0, 0, 255 ); |
| Red | PgHSV( 0, 255, 255 ); |
| Green | PgHSV( 0x5555, 255, 255 ); |
| Blue | PgHSV( 0xAAAA, 255, 255 ); |
| Orange | PgHSV( 0x1400, 255, 255 ); |
| Slate Blue | PgHSV( 0xA000, 121, 134 ); |
