The HSV color scheme consists of three values:
- Hue (base color): between 0 and 360
- Saturation (purity): between 0 and 1
- Value (brightness): between 0 and 1
Here, you can experiment with these values.
The underlying JavaScript code
<jsxgraph width=600 height=500>
var brd = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-2,4,8,-4]});
var H = brd.createElement('slider',[[0,3.5],[5,3.5],[0,1,360]], {name:'H'});
var S = brd.createElement('slider',[[0,3],[5,3],[0,1,1]], {name:'S'});
var V = brd.createElement('slider',[[0,2.5],[5,2.5],[0,1,1]], {name:'V'});
var rct = brd.createElement('curve',[[-1,-1,5,5,-1],[-2,2,2,-2,-2]],
{strokeColor:'black',
fillcolor:function(){ return JXG.hsv2rgb(H.Value(),S.Value(),V.Value()); }
}
);
</jsxgraph>
