in Draw, is there a way to sample a color?

I want to change the background color of a text box to match one of the colors of the picture on which the textbox rests. I’m not sure how to (or if I can) sample the color by clicking on it and then filling the text box with it.
I’m using LO v. on a Windows 10 laptop.
Thanks for your help.

Draw has some eyedropper tool, but only for replacing colours. It does not tell you the rgb or hex value for a colour. I think you will need a third party eyedropper tool. For instance Windows Powertools has a colourpicker. Or you open the image in an image editor that can identify pixel colours.

Thanks. You saved me many hours of experimentation.
