A simple Dart package exposing a Color class which can be used to create, convert, and compare colors.
dependencies: color: any
$ pub get
color.dartfile in your app
Color objects can be constructed using any of a few available constructors.
To create a color from rgb values, call
Color rgbColor = new Color.rgb(192, 255, 238); RgbColor rgbColor = new RgbColor(192, 255, 238);
Alternatively, a color can be created from a string containing a hex value with
Color hexColor = new Color.hex('c0ffee');
Colors can be compared using the
== operator, which will evaluate to true if the two colors share identical rgb values.
assert(new Color.hex('c0ffee') == new Color.hex('c0ffee'));
Colors can be converted from one color space to another by calling the appropriate
toXXXColor method on them.
HslColor hsl = new RgbColor(192, 255, 238).toHslColor();
Colors can be altered using a ColorFilter, which will return a new color in the same color space as the input color with that filter applied to it.
RgbColor grey = ColorFilter.greyscale(new RgbColor(192, 255, 238)); HslColor sepia = ColorFilter.sepia(new HslColor(163.8, 100, 87.6));
0.1.0 ----- * Creation of the Color class supporting rgb colors. 0.2.0 ----- * Added hex support and conversion functions. 0.3.0 ----- * Added hsl support and conversion functions. 0.3.1 ----- * Resolved bug where Color.toHexString() was not prepending each byte with 0s as appropriate. * Added Color.toRgbString() as an alias for Color.toSting(). 1.0.0 ----- * Major refactor which will break code using earlier versions. * Refactored to pull each color space into its own subclass extending a base Color class. 1.1.0 ----- Added XYZ color space support with bidirectional conversions between XYZ and RGB color spaces. 1.2.0 ----- Added CIELAB color space support with bidirectional conversions with the XYZ color space (and the RGB color space using XYZ as an intermediary). 1.3.0 ----- Added toXXXColor() conversion methods for all possible color space transitions. Added Color.clone() method to make a copy of a Color object. Added toCssString() method to RGB, Hex, and HSL colors for easier use with CSS. Added ColorFilters to alter colors according to various filtering rules. Added a demo page to test the package and see the effect of filters.
