Pantone PMS 7545

Submitted by Peter on Tue, 2010-07-13 10:12

Pantone PMS 7545 has no official Pantone name and is known by variations on grey and blue. Case University uses PMS 7545C as the official Case gray. Unofficial names include slate blue, graphite blue, and grey.

PMS 7545 is a theoretical colour and PMS 7545C is a specification for representing the colour on coated paper using specific Pantone inks. PMS 7545M is the specification for representing PMS 7545 on matte paper and PMS 7545U is the specification for uncoated paper. Uncoated paper is washed out, colours appear lighter, and PMS 7545U is probably a good starting point for presenting PMS 7545 on cheap low contrast LCD screens. PMS 7545C should be the starting point for good LCD screens and CRT screens. Matte paper diffuses light more than uncoated paper, making PMS 7545M unsuitable for comparison to any screen.

As an example of how hard colour representation can be, one online chart shows PMS 7545 as a green.
