Larry - there's nothing new under the sun - back in 1988, when I started
doing vehicle inspections for product litigation, I used plastic 6" rulers
with eight of an inch markings along one edge & the other edge marked in
metric - while the entire ruler was essentially a grey card. With 2 of these
in an image, at right angles, you not only could attain proper colors but
also get accurate dimensions in 2 directions.
They are available at -

Subject: Photo gadgets that I wish they made
I've got a set of greycards (white, grey, & black) that are a bit larger
than a business card. I frequently use them to get a white balance
reference, since I'm more likely to shoot in weird lighting than in
"standard" light, such as sunlight, or flash. I recently realized that it
would be really handy if the edges of the grey card were marked in inches
and fractions on one side, and cms & mms on the other. That way, when I
take a photo of it next to a flower, or a bug, to get a white balance
reference, I'd also have something to give a good size reference.
The ideal would be to have a grid of inches or cms, with the fractional
markings along the edge.
Speaking of grey cards, I really wish I could get lens caps, in 18%
neutral grey. That way, I'd always have my white balance reference with
me.
