Re: OT: RHS color charts & yada yada yada

Negatory, not moi. But there have been quite a few published over the years,
as there are quite a few now, even different ones issued by one company, to
meet different needs in different industries or technologies, or regions. And
some charts are revised occasionally to reflect changes in applications,
changes in "pigments", whether actual or virtual, or even changes in aesthetic
fashions in some instances. The differnt systems charts are not identical, nor
do they necessarily have corresponding colors with different names. For
instance, there are theoretically  an infinite number of gradations between
white and black, and so from the lightest tint of a hue to the deepest shade.
But different systems may have different numbers of increments so that one
system's colors may all fall into the "gaps" of those of another system, so to
speak. And it is not just the tints and shades. The steps around the color
wheel may be established in different increments as well. So while any system
with enough colors to be useful will work for you to keep up with your own
stuff, for two people to communicate requires that they each have the same
chart, and the same "edition" of the same chart so that Yellow-yellow-green
Light, or YYG1, or Pamplemousse Mousse, or whatever, means the same thing.
Where it gets hairy is when several charts use the same names for different
colors and you have no idea which one is being referred to in the literature. 

And then there is the little problem of colors looking different in different
light. And to different eyes. And also the little problem of the flowers
developing different colors in different soils, climates and situations.
