PANTONE libraries are distributed in CIE Lab form. Unless the same ICC profiles with the same RI are used on both platforms, there are bound to be differences in RGB / HSB. / Roger -----Original Message----- From: colorsync-users [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of zbet66@yahoo.com Sent: Wednesday, April 18, 2018 3:53 PM To: colorsync-users@lists.apple.com Cc: Glynn Hartley <glynn@specialcolor.com> Subject: Two laptops, two color picker results for same spot I amhaving an experience that I'd like to figure out. I am getting two differentcolor picker readouts for HSB and RGB for the same Pantone spot color on Mac and PC laptops. The Lab and CMYK numbers do match. Pleasenote that all the color management preferences (color settings) are the same on both laptops. Laptop 1:Windows 10 PC Photoshop CC v19.1.0 RGB Default is Adobe RGB Laptop 2:MacBook Pro Mac OS 10.13.2 Photoshop CC v2017.1.0 RGB Default is Adobe RGB Laptop 1,color picker, (example) Pantone Purple RGB= 165,45, 181 CMYK= 35C, 88M, 0Y, 0Y HSB:293/75/71 Lab: 47/69/-42 Laptop 2,color picker, (example) Pantone Purple RGB= 144,65, 160 CMYK= 35C, 88M, 0Y, 0Y HSB:290/59/63 Lab: 47/69/-42 Laptop 1,color picker, (example) Pantone 802 RGB=128/212/69 CMYK= 67C, 0M, 100Y, 0Y HSB: 95/67/83 Lab: 75/-63/63 Laptop 2,color picker, (example) Pantone 802 RGB=117/189/73 CMYK= 67C, 0M, 100Y, 0Y HSB:97/61/74 Lab: 75/-63/63 This istrue of all spot colors. (both are Pantone+ Solid Coated library) Why? The PCversion looks to be correct. Why is the Mac version giving different numbers inRGB and HSB?
