Built from WC-Generator v3.9.3

Useful Function For later:

In the event that rgba values are passed in and need to be converted to hex values to hit the wcag api(currently 6/2021 the WCAG api doesn't not accept 8 char hex values) then this function may prove useful for converting rgb/rgba values to hex.

   * @private internal function
   * @param {string} rgb(a) value string ex "rgba(0,22,23,0.5)"
   * @returns {string} 7-8 char hex value ex "#00161780"

  rgbaToHex(rgbaString) {
    // remove whitespace
    rgbaString = rgbaString.replace(/\+/g,'');
    // find indices of parentheses
    const valuesStart = rgbaString.indexOf('(')+1;
    const valuesEnd = rgbaString.indexOf(')');
    // pull rgb(a) values out into an array and convert them to decimal
    let rgba =  rgbaString.substring(valuesStart, valuesEnd).split(',').map(x=>+x);
    if(rgba.length == 4) {
      rgba[3]=Math.round(rgba[3] * 255);
    rgba = rgba.map(x => {
      // convert to hex;
      x = x.toString(16);
      // add 0 to single char values
      if (x.length==1) {
        x = "0" + x;
      // update array
      return x;

    return "#" + rgba.join('');
