Hexa color code generation from any text string

JavaScript - RGB char code based

function generate_color_from_text(text) {
  var redRandom = 0;
  var greenRandom = 0;
  var blueRandom = 0;

  for (var i = 0; i < text.length; i++) {
      var charCode = text.charCodeAt(i);
      redRandom += charCode;
      greenRandom += charCode+1;
      blueRandom += charCode+4;
  }

  redRandom = 40 + (redRandom % 5) * 40;
  greenRandom = 40 + (greenRandom % 5) * 40;
  blueRandom = 40 + (blueRandom % 5) * 40;

  return "#" + componentToHex(redRandom) + componentToHex(greenRandom) + componentToHex(blueRandom);
}

function componentToHex(c) {
    var hex = c.toString(16);
    return hex.length == 1 ? "0" + hex : hex;
}

Ruby - hash based version

require 'digest'

def generate_color_from_text(text)
  hexd = Digest::MD5.new.update(text.to_s).hexdigest
  hexa_color_str = '#' + hexd[0,2] + hexd[2,2] + hexd[4,2];
  return hexa_color_str
end

Ruby - RGB and char code based version (with per-channel clamping)

def generate_color_from_text(text)
  red, green, blue = 0, 0, 0
  
  text.each_char do |char|
    charCode = char.ord
    red += charCode
    green += charCode+1
    blue += charCode+4
  end

  red = 40 + (red%45)*4
  green = 40 + (green%45)*4
  blue = 40 + (blue%45)*4

  hexa_color_str = "#%02x%02x%02x" % [red, green, blue]
  return hexa_color_str
end
