What is Colorsys.jl

Colorsys.jl is a Julia package(or lib) for everyone to transform one color system to another. The transformation is among RGB, YIQ, HLS and HSV.

How to use it

Parameter Range

All inputs and outputs are three floats in the range [0.0...1.0] (with the exception of I and Q, which covers a slightly larger range also with the exception of R, G and B, which range from 0 to 255 also with the exception of H, which range from 0 to 360).

range of each parameter
R, G, B :    0 ~ 255
I, Q :      -1 ~ 1.X
H :          0 ~ 360
Y, S, V, L : 0 ~ 1

Examples

1. RGB to YIQ

y, i, q = rgb2yiq(r, g, b)

2. YIQ to RGB

r, g, b = yiq2rgb(y, i, q)

3. RGB to HLS

h, l, s = rgb2hls(r, g, b)

4. HLS to RGB

r, g, b = hls2rgb(h, l, s)

5. RGB to HSV

h, s, v = rgb2hsv(r, g, b)

6. HSV to RGB

r, g, b = hsv2rgb(h, s, v)

7. Yiq to Hls

h, l, s = yiq2hls(y, i, q)

8. YIQ to HSV

h, s, v = yiq2hsv(y, i, q)

9. HLS to YIQ

y, i, q = hls2yiq(h, l, s)

10. HLS to HSV

h, s, v = hls2hsv(h, l, s)

11. HSV to YIQ

y, i, q = hsv2yiq(h, s, v)

12. HSV to HLS

h, l, s = hsv2hls(h, s, v)
