Expand description

The most common DeltaE methods

## Variants

`DE2000`

The default DeltaE method

`DECMC(f32, f32)`

### Tuple Fields of DECMC

`0: f32`

Lightness tolerance

`1: f32`

Chroma tolerance

`DE1994G`

CIE94 DeltaE implementation, weighted with a tolerance for graphics

`DE1994T`

CIE94 DeltaE implementation, weighted with a tolerance for textiles

`DE1976`

The original DeltaE implementation, a basic euclidian distance formula
