Question

Below is a function to convert rgb to hex color. But it is not totally correct. With (0, 255, 0) (#00ff00). it return ff00 and so it is not valid color. I need help to modify it to return correct hex value.

function rgbToHex(r, g, b) {
        var rgb = b | (g << 8) | (r << 16);
        return rgb.toString(16);
    }

Answer 1

How about this:

//...
return (0x1000000 | rgb).toString(16).substring(1);
