• Well,

try this one for the moment:

``````  let ScreenWidth  = g.getWidth(),  PatchWidth  = ScreenWidth/6;
let ScreenHeight = g.getHeight(), PatchHeight = ScreenHeight/6;

g.clear();

for (let i = 0; i < 27; i++) {
let x = (i % 6)         * PatchWidth;
let y = Math.floor(i/6) * PatchHeight;

let R = i % 3;
let G = Math.floor(i/3) % 3;
let B = Math.floor(i/9);

g.setColor(R/2,G/2,B/2);
g.fillRect(x,y, x+PatchWidth-1,y+PatchHeight-1);
}

g.setFont12x20();

Bangle.on('touch', function (Button,Position) {
let x = Math.floor(Position.x / PatchWidth);
let y = Math.floor(Position.y / PatchHeight);

let i = y*6 + x;
if (i >= 27) { return; }

let R = i % 3;
let G = Math.floor(i/3) % 3;
let B = Math.floor(i/9);

let HexValues = ['00','80','FF'];

g.setColor(1,1,1);
g.fillRect(3*PatchWidth,4*PatchHeight, ScreenWidth,ScreenHeight);

g.setColor(0,0,0);
g.drawString(
'#' + HexValues[R] + HexValues[G] + HexValues[B],
3*PatchWidth,4*PatchHeight+6
);
});
``````

I'll make a "real" application out of it as soon as I find the time (it's Christmas right now, you know...time for the family)
