Default A/C oil leak?

Is this an A/C oil leak? Car was sitting for a few weeks I let it run and took it out and noticed had oil on the ground bright yellow. Don't see it leaking anymore yet. Just an odd spot not sure the source,

Yeah I agree maybe it's PAG oil with UV dye. That one is Greenish yellow. It was sticky also. Haven't noticed any more leaking though.

A/C working and blowing ice cold had it running on high for a bit. Have to see if it leaks again in that area.

Dye would only be in the AC system if the system was diagnosed for a leak (doesn't come from GM with dye in the system).

20 years ago my 2001 Z06 had a similar oil leak showing on the bottom engine cradle. Dealer diagnosed that it was not engine oil (dye check) and baffled as to where it was coming from. AC was blowing cold and thus would appear not to be an issue. Nonetheless, shop mgr rolled the dice and replaced the AC compressor. Mystery solved as AC performance was normal even after having lost so much refrigerant oil but the leak was from the compressor.
