I'm feeling blue

1/21/2021

Now just hold on. I've heard it during the broadcast and now read it again that K. Harris wore a purple dress to honor the first black woman who ran for president.

But ... it wasn't purple. Unless there was a color shift on my display (always possible) the dress was blue. A real RGB blue - not cyan or sky blue but a spectral blue. Which, I'll agree, is a warm blue (hence further along the spectrum toward infrared but ... still blue). Takes more of a red shift for it to qualify as "purple". 

Can I test it? Sure! In the world of digital color it's easy. Just take a screenshot, load it into a graphics program like Procreate, and sample the image. This then brings up a nice color gamut display and the sampled pixel's place within it.. As you can see, the sample is solidly blue. On neighborly terms with purple but only that. Just neighbors.

Color is forever

Or ... is it?

When you go to a paint manufacturers website they'll usually list the properties of the watercolors they sell. And one of those properties is how lightfast, or fugitive, or perennial it is. All words that refer to "Does the color fade with exposure?"

There's an official organization that test them. But not everyone uses it and not all colors have been evaluated. And just how much worse is a 1 than a 2 than 3 on their scale?

That's what this is for. A page of swatches of a variety of watercolor paints, ranging from excellent to totally crummy in terms of lightfastness. My plan is to cut it in two, put one half in a drawer and expose the other to sunlight all day long. Day after day. How long do you expect it to be before I see a difference? I have no idea but I'm about to find out!
