Converts hex to sRGB Returns an array of the form [r,g,b] where r, g, and b are integers between 0 and 255

prow.convert.hexToRGB("#fff"); // Returns [ 255, 255, 255 ]

Hex can be:

• "fff"
• "ffffff"
• "#fff"
• "#ffffff"
• "0xffffff"

Converts sRGB to hex where rgb is an array of the form [r,g,b] where r, g, and b are integers between 0 and 255 Returns a string of the form "#ffffff"

prow.convert.RGBToHex([255, 255, 255]); // Returns #ffffff

Converts sRGB to linear RGB where rgb is an array of the form [r,g,b] where r, g, and b are integers between 0 and 255 Returns an array of the form [r,g,b] where r, g, and b are decimals between 0 and 1

prow.convert.RGBToLinearRGB([255, 255, 255]); 
// Returns [0.003676507324047436,​​​​​​​​​​ 0.004024717018496307,​​​​ 0.024157632448504756 ]​​​​​

Returns a decimal value representing the relative luminance of the given color. Color must be an sRGB array of the form [r,g,b]

prow.getRelativeLuminance([255, 255, 255]); // Returns 0.9873055935982454​​​​​

Returns the contrast ratio of the two given colors in fractional form. Takes two parameters which must be sRGB arrays of the form [r,g,b]

prow.getContrastRatio([255,253,255], [1, 1, 1]); // Returns ​​​​​20.620931688099795
