## color
- A V library for working with colors
- Support for
> - sRGB(A)
> - HSL(A)
> - CMYK
> - Hex (with optional alpha)
> - CIELAB
> - AdobeRGB(A)
> - LCH
### Usage
`v install werdl.color`
```v
import color
fn main() {
rgb:=color.rgb(160,225,43)
println(rgb.cmyk())
println(rgb.hex())
}
```
```v
// A list of all methods
// Constructors
rgb(r int, g int, b int) -> RGB
rgba(r int, g int, b int, a f64) -> RGB
hsl(h int, s int, b int) -> HSL
hsla(h int, s int, b int, a int) -> HSL
adobergb(r int, g int, b int) -> AdobeRGB // normalised to 255
adobergba(r int, g int, b int, a f64) -> AdobeRGB
cmyk(c int, m int, y int, k int) -> CMYK
cielab(l f64, a f64, b f64) -> CIELAB
lch(l f64, c f64, h f64) -> LCH
hex(x int) -> HEX // 3, 6 or 8 digit hex number
hex_s(s string) -> HEX // same spec

### XYZ tristimulus values
- We use Illuminant D65 with the standard 2° observer
$X_n=95.0455927$
$Y_n=100.0$
$Z_n=108.905775$
### Note
- This library involves conversion between different color types (obviously), including non-linear conversion.
- That means that while it is fairly accurate, it is not perfect!
- To avoid this as far as possible, try to use RGB as the medium, which has the actual calculations between the complicated formats!
