We’ve talked about ordinary time green on this site before.
I have new co-chairs for AED (art/environment/decoration) in my new parish. I was happy with their work for summer ordinary time. Even though I’m not a fan of light green shades for vestments, I rather liked what they uncovered in storage.
Sit in the (not light) purple chair and render judgment. Light green too light? The white highlight?
What about the holiday display? (This screenshot was from our July 3rd Sunday Mass. and yes, we did have a flag too.)
How much matchy-matchy do you think is needed with clergy vestments?

I call that celadon (a jade-related hue/tone). Not a liturgical green. Then again, environment like that is not vestments and altar paraments that are customarily closed tied to vestments, and need not match. So long as folks are encouraging the PIPs to vest similarly, I can be agnostic.
Btw, the Latin for liturgical green is viridis, which is the typical range of color of fresh vegetation. A paler blue-green is prasinus, which is not a liturgical green. (Latin remains relevant for interpreting the meaning of the English docs!)
