Pantone PMS 382

Submitted by Peter on Wed, 2010-06-23 23:44

Pantone PMS 382 is known as Lime, Spring green, PMS 382C, PMS 382M, and PMS 382U in various documents.

PMS 382 is a theoretical colour and PMS 382C is a specification for representing the colour on coated paper using specific Pantone inks. PMS 382M is the specification for representing PMS 382 on matte paper and PMS 382U is the specification for uncoated paper. Uncoated paper is washed out, colours appear lighter, and PMS 382U is probably a good starting point for presenting PMS 382 on cheap low contrast LCD screens. PMS 382C should be the starting point for good LCD screens and CRT screens. Matte paper diffuses light more than uncoated paper, making PMS 382M unsuitable for comparison to any screen.

#c1d82f

CQUniversity (Central Queenland University) use Pantone PMS 382C in their logo and specify the HTML representation as #c1d82f, the colour used for this paragraph. The specify the following representations in various colour systems.
PMS 382C
CMYK: 29/0/100/0
RGB: 193,216,47
HTML: #c1d82f
 
An image editing program says #c1d82f represents the following settings.
CMYK: 11/0/78/15
RGB: 193,216,47
HSV: 68 78 85

29/0/100/0

Several organisations list Pantone PMS 382C as CMYK: 29/0/100/0 and do not specify the HTML representation.

When I enter CMYK: 29/0/100/0, I get the following representations, different from the CQUniversity list.
RGB: 181,255,0
HTML: #b5ff00 (the colour used for this paragraph)
HSV: 77 100 100

#b6c827

Another organisation lists PMS 382C as;
CMYK: 40/0/100/0
RGB: 182,200,39
HTML: #b6c827 (the colour used for this paragraph)

40/0/100/0

When I enter CMYK: 40/0/100/0, I get the following representations.
RGB: 153,255,0
HTML: #99ff00 (the colour used for this paragraph)
HSV: 84 100 100
 
One nice book on colour, printed colour, lists CMYK 40/0/100/0 as Campus Green and says the colour is lively, healthy, peaceful, active, and youthful. The colour shown in their book looks close to the #bad80a used in the next paragraph but not like the #99ff00 used in this paragraph.

#bad80a

This paragraph uses #bad80a for PMS 382C as suggested in another colour chart. #bad80a is a popular interpretation of PMS 382C and I suspect a lot of the charts were copied from each other.

LCD viewing angle

When you test a colour on screen, view the colour from several angles. When I move my head to the left or right side of my LCD screen, the green becomes a yellow brown tint. The green looks yellow when viewed from a low angle and a dark green looking down from the top. My screen is medium desktop size, 26", and full height, not a short widescreen thing. The shape matches the human range of vision instead of some movie format. The screen is big enough for the colour at the edges to look slightly different to the colour in the middle because of the different viewing angles.

Apple legacy

Apple computers used, for a long time, non standard display settings, specifically gamma. One day Apple woke up, smelled the profit they could make selling ordinary PC at inflated Apple prices, and suddenly Apple computers had a standard gamma setting. Unfortunately a lot of the HTML colour specifications in Web pages were made by people using the old Apple hardware and have to be updated to this century.

Other greens

PMS 368 is named Apple green.

Conclusion

Make up your own mind about the best screen colour to represent the colour you use for printed material, uniforms, signs, vehicles, and everywhere else. Test the HTML colour on a lot of screens including all the different Internet connected telephones.
