HiliteGradient

// basic usage

(

w = Window.new.front;

v = CompositeView(w, Rect(50, 50, 200, 50));

v.background = HiliteGradient(Color.gray, Color.white);

)

​

// change direction and resolution

(

w = Window.new.front;

w.view.background = HiliteGradient(Color.red, Color.white, \h, 12, 0.5);

)

​

// almost unnoticeable variations can be pleasant

(

w = Window.new.front;

v = CompositeView(w, Rect(50,50,300,300));

c = Color.rand;

d = c.vary(0.15);

v.background = HiliteGradient(c, d, \v);

[c, d].postln

)

​

(

var w, k, c, d, e, c1, c2, f, g;

w = Window.new.front;

k = Slider2D(w, Rect(50, 50, 300, 300));

f = {

    c = Color.rand;

    d = c.vary(0.5);

    e = d.vary(0.5);

};

g = {

    c1 = d.hueBlend(e, k.y).round(0.01);

    c2 = c.hueBlend(e, k.x).round(0.01);

    k.background = HiliteGradient(c1, c2, \v)

};

f.value; g.value;

k.action = g;

k.mouseUpAction = { [c1, c2].postln };

k.keyDownAction = f; // hit any key for new color
