Hi,

I'm afraid that is currently not possible. I do think you can mimic the behavior by introducing a Conditional layout that set the backround and font color to the same value, but understandably that is a bit of a workaround. Feel free to create an idea for this.

Do not that Universal has a Light and Dark mode. Not all colors would be suitable in a Grid to be used in the way as in the Windows GUI. For instance you could use the Dark grey or Black color in a Grid to indicate an inactive situation, but that color in Dark mode in Universal would vanish.

You can set up a bit of custom CSS to achieve this:

/* Hide the text in grid color inputs */

.tsf-grid-cell span:has(input[type="color"]) {
  font-size: 0px;
}
