For M(aterial)3 the new HTC color system has been created, that
|
||
|
|
is based on H(ue), (C)hroma, (T)one:
|
||
|
|
|
||
|
|
https://material.io/blog/science-of-color-design
|
||
|
|
|
||
|
|
This system allows to create color palettes by varying the tone
|
||
|
|
for given hue/chroma values.
|
||
|
|
|
||
|
|
https://material-foundation.github.io/material-theme-builder/#/custom
|
||
|
|
shows how to create a tonal palette from a given RGB color.
|
||
|
|
|
||
|
|
The methods in QskHctColor allow to do the same:
|
||
|
|
|
||
|
|
QVector palette( const QRgb rgb )
|
||
|
|
{
|
||
|
|
double hue, chroma;
|
||
|
|
QskHctColor::getHueAndChroma( rgb, hue, chroma );
|
||
|
|
|
||
|
|
QVector< QRgb > pal;
|
||
|
|
for ( int tone = 0; tone <= 100; tone += 10 )
|
||
|
|
pal += rgbFromHct( hue, chroma, tone );
|
||
|
|
|
||
|
|
return pal;
|
||
|
|
}
|
||
|
|
*/
|
||
|
|
|
||
|
|
namespace QskHctColor
|
||
|
|
{
|
||
|
|
QSK_EXPORT QRgb rgb( double hue, double chroma, double tone );
|
||
|
|
QSK_EXPORT void getHueAndChroma( QRgb rgb, double& hue, double& chroma );
|

}
