There's something very wrong with the color guide tool panel. It's showing completely incorrect swatches, the preview thumbnails in drop down do not match at all the actual colors when you open a palette, and some of the palettes have jumbled colors.

This is happening to me as well. 

May I request ​@Nico Flores , ​@jenniferb95816151 and ​@perdelima to kindly vote on this as well using the vote button on the original post? This helps in priortizing. 

this is happening to me too and it’s really frustrating since i use it a lot

​@Smriti Capoor it’s happening with the latest stable build, 30.5.1. When I initially reported it, I think it was the Beta build just before the latest Beta build. I’d tell you the exact version but I don’t want to open the Creative Cloud desktop app because it causes too many issues. 

​@udderball / ​@jenniferb95816151 / ​@perdelima can you please provide me build details? Which Beta build are you facing this on?

Thank you for reporting this. I have raised a ticket for this and it is being investigated.

this is happening to me too.

Hello ​@udderball thank you for reporting this. Can you please let me know the Beta build number?

Yes this is happening to me too. The colour display for Colour Guide are all wrong.
