docs: Validates whether an input color is a valid color of type
  <code>sap.ui.core.CSSColor</code> or <code>sap.ui.core.IconColor</code>.
  undefined, null and an empty string are also valid.
  In case the color is not valid, an error gets logged to the console.
  
  @param {sap.ui.core.CSSColor|sap.ui.core.IconColor|null|undefined|string} vColor input color.
  In case a string value other than <code>sap.ui.core.CSSColor</code>
  or <code>sap.ui.core.IconColor</code> is passed, only an empty string is a valid value.
  @returns {boolean} True in case the color is valid and false in case it is not valid.
