I guess I should add some comment in here, since I frequently speak on color trends at design conferences, and am a color forecaster for trends with the Pantone Color Insititute, along with Leatrice Eiseman and the Color Carketing Group. And, in my day job, as Creative Director at Hasbro, the toy Company. So color is one of my 'things'. Color theory is complex, and it seems that after reading much of what has been said, many of you are indeed correct. Lee, of course, yes, refraction from daylight, white paper and light source quality all affect color. As with paint colors and pigment for interiors, if the grass is green outside and the sun is shining, your white walls can appear green. Awaken on a snowy morning, and suddenly everything is more bright. Color is affected both by it's projection, and by how it is lit. With organic structures, we need to consider refraction within the cells, a complex phenomenon that we can never truly recreate on paper. Why is the sky blue? Mark, yes and no. The color picking feature in Adobe Photoshop, Illustrator or any digital design program, is hardly accurate beyond the printed number. But I agree, it could be effective enough to communicate across the seas and on this site. Also to take into consideration is that digital color is backlit, and a monitor color is literally glowing. Besides, the fact that there is RGB, Gamma warnings, and CMYK to consider. I require that our designers select and proof color under controled settings, in a light room specially created for color proofing. They then send along a hard Pantone chip (or Heaxacolor, or hexachrome or Toyo - this is why there are so many color palettes in Photoshop, even the color industy can't decide who has the best selection. Some have better greens, some have better oranges. Since, no effective and agreed upon universal calabration system exisits, we still rely on a Pantone chip, but making certain that we assign an ink chip for an ink on paper project or a plastic chip for plastic, a fabric chip for fabric, you get the picture. They just don¹t make a petal chip. So, I think that you are smart to agree on simply by giving the numbers, we should be able to get close enough without the RHS chart. That's if you don't have the chart. In my business, we use transparent pantone chips on plastic for blown plastic product, fabric Pantone chips, metal chips,glass chips, enamal chips, every industry has an agreed upon system. And that tells us something. Also, and any graphic designer will tell you about the differences between a coated paper, and an uncoated paper Pantone chip. A 300 blue will seem different every single time, unless you are using a new box of chips, and they haven't faded, and you are printing on the same paper. What color is Nerine sarniensis Corusca Major? Nature invented the finest and most complex coloring system. I challenge anyone to find the Pantone chip or the RHS chip for the color of the sky that we could all agree on....and let's face it, the sky. And the sun, are the light source that we all proof on. My opinion, is to invest in the RHS color chart, it is, by far, the best and most accurate, yet, in some strange way, not even close. My take on Puce.....Our color conference color of choice is that muddy dusty pink color that they used in 1980's Rubbermaid products and is a truly light puce, we call it, simply, .....Veal.
