README
hsi.js is a small javascript library which converts HSI and RGB to each other.
## Examples
### Conversion from RGB to HSI
hsi = toHSI(255, 0, 0); // [0, 1, 0.3333]
you can use various RGB formats.
hsi1 = toHSI(255, 0, 0);
hsi2 = toHSI([255, 0, 0]);
hsi3 = toHSI('#FF0000');
hsi4 = toHSI('#ff0000');
hsi5 = toHSI('rgb(255,0,0)');
// all results will be the same. [0, 1, 0.3333]
### Conversion from HSI to RGB
rgb1 = toRGB(0, 1, 0.3333); // [255, 0, 0]
rgb2 = toRGB([0, 1, 0.3333]); // [255, 0, 0]
pink = toRGB(300, 1, 0.6666); // [255, 0, 255]
### Other Usages
you can generate colors using HSI features.
//generate pastel-tone color.
pastel = toRGB(Math.floor(Math.random() * 360), 0.3, 1);
//generate vivid color.
vivid = toRGB(Math.floor(Math.random() * 360), 1, 1);
