A brighter shade of yellow

I've been trying to find a photo to illustrate this, but I'm failing at the moment. When I do find the picture, or take one, I'll post it so you can see what I'm talking about.

On some recent sign installations in Kentucky, there's a distinct difference in color/brightness between the yellow warning sign and the yellow advisory speed plate beneath the warning sign.

Is this a difference in color? In reflectivity standards? Or both?

The first place I saw the brighter yellow signage in use was in Georgia, back in 2008 or 2009.It has only made it to Kentucky in the last 3-4 years.
Government would be tolerable if not for politicians and bureaucrats.

I rather doubt it's intentional. They probably don't care much about the exact color, just so long as someone would call it "yellow".

I got some photos today (with my phone under overcast conditions) to illustrate what I'm talking about.

All these assemblies were installed at the same time.

Interesting.  Do they have a stockpile, perhaps?  It looks almost like the diamond signs are older and the plaques are newer.  If the diamond signs came from a stockpile but the plaques had to be made, that could explain it.

Perhaps there was a different manufacturer for the reflective sheeting.

I've seen this issue some in West Virginia. Contractor-installed signage tends to be a slightly brighter yellow than WVDOH-manufactured signage.

On I-68 eastbound at Exit 1, the exit gore sign had its top half with the EXIT text replaced after being damaged by a hit. The original sign was contractor-installed but the replacement top half was handled in-house. There are some subtle differences in the shade of green, although I'm not sure if that is from differences in the sheeting itself or just aging from the sign being outside for a couple years.

The diamond panels probably just sat around in the sign shop for a longer time before they were installed. It's normal for sign shops to have a stockpile of lots of common signs. This is the reason why my workplace has a lot of assemblies exactly like this in the field: the advisory speed plaques are brighter than the top diamond panel.
