An unquantized color is a triple of 32 bits floating point values representing continuous color components. All component values are defined in the [0..1] interval, with the following exceptions:
- YUV: U and V in range [-0.5..+0.5]
- YIQ: I and Q in range [-0.5..+0.5]
- L*a*b*: L* in range [0..100[, a* and b* in range [-128..+128]
- LCH: L in range [0..100[, C in range [0..256[
- L*u*v*: L* in range [0..100[, u* and v* in range [-128..+128]
The hues are computed in revolutions rather than degrees and thus contained in the [0..1] interval as well.
