## DESCRIPTION

**This class is used to represent an RGB color. Each component of the vector is a floating-point number between 0.0 and 1.0. There are routines to convert back and forth between RGB and HSV.**

## METHODS

	**SbColor(const SbVec3f vec3f)**\
 	**SbColor(const float rgb\[3\])**\
 	**SbColor(float r, float g, float b)**\
 Constructors for color vector.

**SbColor &**	**setHSVValue(float h, float s, float v)**\
 Sets value of color vector from 3 HSV (Hue, Saturation, and Value) components. Value is the same as brightness of the color.

**SbColor &**	**setHSVValue(const float hsv\[3\])**\
 Sets value of color vector from array of 3 HSV components

**void**	**getHSVValue(float &h, float &s, float &v) const**\
 Returns 3 individual HSV components

**void**	**getHSVValue(float hsv\[3\]) const**\
 Returns an array of 3 HSV components

**SbColor &**	**setPackedValue(uint32\_t rgba, float& transparency)**\
 Sets value of color vector from an RGBA packed color value. The packed color format expressed in hexadecimal is 0xrrggbbaa, where

```
	rr is the red value
	gg is the green value
	bb is the blue value
	aa is the alpha value
```

RGBA component values range from 0 to 0xFF (255). The returned transparency value is a floating point value between 0.0 (opaque) and 1.0 (completely transparent). It is derived from the alpha component of the RGBA color.

**uint32\_t**	**getPackedValue(float transparency = 0.0) const**\
 Returns an RGBA packed color value, derived from the color vector and the passed transparency value. The alpha component is set to (1.0 - transparency) \* 255, resulting in a hex value between 0 and 0xFF. If transparency not specified, alpha is set to 0xFF (opaque).
