This is a javascript library for converting colors between different color formats. It supports rgb, hsl, and hsv. To call a method of the library simply say colorCommon.methodName(). Valid color strings can take one of the following formats: #00FF00, rgb(0, 255, 0), rgb(0%, 100%, 0%), hsl(120, 100%, 50%), hsv(120, 100%, 100%). If a non-valid color string is passed in an "InvalidColorValue" exception is thrown
API
toHex
gets a Hex string for a color
parameter:
- any valid color string
return:
- a string of the color in hex format
example:
colorCommon.toHex("hsl(142, 45%, 10%)");
toRgb
gets an Rgb string for a color
parameter:
- any valid color string
return:
- a string of the color in rgb format
example:
colorCommon.toRgb("hsv(230, 100%, 10%)");
toPercent
gets an Rgb string in percentile format for a color
parameter:
- any valid color string
return:
- a string of the color in rgb percentile format
example:
colorCommon.toRgb("#66CCE4");
toHsl
gets an hsl string for a color
parameter:
- any valid color string
return:
- a string of the color in hsl format
example:
colorCommon.toHsl("#66CCE4");
toHsv
gets an hsv string for a color
parameter:
- any valid color string
return:
- a string of the color in hsv format
example:
colorCommon.toHsv("#66CCE4");
rgbValues
gets the individual red, green, and blue values for a color string
parameter:
- any valid color string
return:
- an object with properties red, green, and blue
example:
colorCommon.rgbValues("#66CCE4")["red"];
hslValues
gets the individual hue, saturation, and lightness values for a color string
parameter:
- any valid color string
return:
- an object with properties hue, sat, and light
example:
colorCommon.hslValues("#66CCE4")["light"];
hsvValues
gets the individual hue, saturation, and value values for a color string
parameter:
- any valid color string
return:
- an object with properties hue, satv, and val
example:
colorCommon.hsvValues("#66CCE4")["satv"];
isValid
reports whether a color string is a valid color
parameter:
- any color string
return:
- true if it is a valid color, false otherwise
example:
colorCommon.isValid("rgb(4000,,)");
isValid
reports whether a color string is a valid color
parameter:
- any color string
return:
- true if it is a valid color, false otherwise
example:
colorCommon.isValid("rgb(4000,,)");
luminosity
gets the WCAG luminosity for a color.
parameter:
- any valid color string
return:
- a decimal number from 0 to 1 (0 is black, 1 is white)
example:
colorCommon.luminosity("#445590");
contrast
gets the WCAG luminosity contrast ratio for a color.
parameter:
- any valid color string
return:
- a decimal number from 0 to 21 (4.5 is considered minimum for text/background ratio, 7 is good, and 10+ is excellent)
example:
colorCommon.contrast("hsl(46, 100%, 34%)", "#445590");
