Colour picker option is not working in the latest XD Version.

Hi @MAHESH588 , I'd suggest trying @HARSHIKA_VERMA's suggestion here for now:

"..We would request you to please try launching your window from your native display. If that doesn’t work, you may try switching your monitor in your Display settings to sRGB."

Also maybe sharing your operating system etc details might be helpful for the experts to be more helpful. Hope this helps!
