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.

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.

setHSVValue(const float hsv[3])
Sets value of color vector from array of 3 HSV components
c
}
c
}
getHSVValue(float &h, float &s, float &v) const
Returns 3 individual HSV components
c
}
c
}
getHSVValue(float hsv[3]) const
Returns an array of 3 HSV components
c
}
c
}
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.
c
}
c
}
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).
