RGB to hex and hex to RGB

Question

How to convert colors in RGB format to hex format and vice versa?

For example, convert \'#0080C0\' to (0, 128, 192).

Answer 1

i needed a function that accepts invalid values too like

rgb(-255, 255, 255) rgb(510, 255, 255)

this is a spin off of @cwolves answer

function rgb(r, g, b) {
  this.c = this.c || function (n) {
    return Math.max(Math.min(n, 255), 0)
  };

  return ((1 << 24) + (this.c(r) << 16) + (this.c(g) << 8) + this.c(b)).toString(16).slice(1).toUpperCase();
}
