Color palette overrides fill colors and color modes in Illustrator 2018
Hi, I am a design professor and most students in my class experienced a specific problem when we were doing an exercise to learn how to apply the correct color palettes to different logo files. Specifically, we created fictional identity designs as a means to learn how to create a production-ready bundle of files (a logo with versions in b&w, spot color (Pantone), 4-color process, and RGB). Almost 100% of my 18 students had their 4-color process file -- which was filled with CMYK colors upon designing, and should have stayed CMYK -- show up as being filled with RGB when opened after having been closed.
Through testing this unusual pattern of error across all of their files, it appears that Adobe Illustrator will choose to show colors in the color palette that was last opened within the application, and if the palette isn't the same as the fill colors, it creates a color translation of what the color should be into what it want to show you. Stated another way, the students had trouble getting the color palette to hold the color information they entered (percentages/values of either CMYK or RGB, in particular). Regardless of what they had entered, a computer with one or the other of these color palettes open would override their settings. Unacceptable. In one case, I also witnessed a student manually enter RGB values, only to deselect the item, select the object again, and then find different RGB values in place than those I watched him enter. In 19 years of teaching, I've never seen this problem be so widespread across student files.
For what it's worth, the Pantone palette behaved. The problem specifically is between RGB and CYMK colors/color palettes. PLEASE FIX THIS. This will cause major problems in real projects that rely upon color mode accuracy. Please contact me with information about the problem and/or solution. We would appreciate a follow-up.
Just spent three hours trying to figure this out....so frustrating! Even though the graphic file shows I've switched to CMYK the only option I have to choose from for the fill is RGB or K.
