Color Cue 2

PS hex = RGB. Pantone (process) is 4-color aka CYMK (additive vs subtractive color) - so it won’t be a perfect match, but then again web design is kinda a “close enough” medium, considering there’s no guarantee of anything but that the end-user will probably NOT have a properly calibrated monitor… you’re better off asking the client “who did the logo / art, what are the PMS colors” anyway.
