Option to Select Transparent Text Color

Power Bi does not have the option to set the Text Color of headers to be transparent (#ffffff00).

They also do not have the ability to set the grid outlineColor to be transparent (#ffffff00)

You could accomplish this through the following json code:

   "fontColor": { "solid": { "color": "#ffffff00"}}

however, the latest PowerBi release only allows hex codes that meet the following regex criteria:

"color must match pattern "^#([a-fA-F0-9]{3}){1,2}$""

This release has broken the custom ability to set colors to the transparent hex code "#ffffff00"

If it cannot be done through JSON, please allow transparent to be a selectable option in the color picker for text.
