A Dart plugin for defining color constants and converting them between color spaces.
For use with Flutter, see: http://github.com/james-alex/flutter_color_models
Color Spaces #
color_models exposes models for the CMYK, HSI, HSL, HSP, HSV, LAB, RGB, and XYZ color spaces; represented as [CmykColor], [HsiColor], [HslColor], [HspColor], [HsvColor], [LabColor], [RgbColor], and [XyzColor] respectively.
Each model is constant and extends [ColorModel].
Converting Colors Between Spaces #
Each color model has methods to convert itself to every other color model.
CmykColor toCmykColor(); HsiColor toHsiColor(); HslColor toHslColor(); HspColor toHspColor(); HsvColor toHsvColor(); LabColor toLabColor(); RgbColor toRgbColor(); XyzColor toXyzColor();
Altenatively, each color model has a static method
from that can
accept a color from any color space and returns its own type (T).
static T from(ColorModel color);
// Create a HSV color HsvColor originalColor = HsvColor(0.3, 0.8, 0.7); // Convert it to RGB => RgbColor(64, 179, 36) RgbColor rgbColor = RgbColor.from(originalColor); // Then to CMYK => CmykColor(64.25, 0, 79.89, 29.8) CmykColor cmykColor = CmykColor.from(rgbColor); // Back to HSV => HsvColor(0.3, 0.8, 0.7) HsvColor hsvColor = HsvColor.from(cmykColor);
Note: All color conversions use the RGB color space as an
intermediary. To minimize the loss of precision when converting
between other color spaces, [RgbColor] privately stores the RGB
values as [num]s rather than [int]s. The [num] values can be
returned as a list with [RgbColor]'s
