Yellow background panel to text for max

I wish for some warning text to be hi visiblity max impact and red text on a yellow base is good, however if I make a planar surface under the text and place it on a layer that is given yellow, its a dull muddy yellow in ortho view.

How can I make the background of the text bright yellow ?

What ways are there to make some text really stand out ? Bold is not enough at times.


Check out the possibility of a text mask in Properties…

and if Mitch’s solution doesn’t do it for you, try a solid hatch in a rectangle (or other polyline shape) instead of a planar surface.
