I work with multiple brands, creating eDMs, flyers and posters. To be able to maintain Brand Integrity across all my media, I need to often refer to the CMYK or RGB charts given in each brand's color guidelines.
Instead of creating individual swatches to import once I start a project, I was thinking I could create vector squares of the color palette, and export it as a medium-quality PNG to import into Ai for me to use the color-dropper on elements that then require these brand colors.
What I haven't been able to find out online, is if I do this, will the colors change if I eye-drop from a PNG?
Bear in mind that this is all before printing/exporting into JPEG or PDF.
