The manufacturer of Staroplzenecký Absinth strongly insisted to me that this product is colored with chlorophyll. The labeling clearly states that E102 and E133 are used.
E102 is the European code for Tartrazine, also known as FD&C yellow No.5 in the US. According to ukfoodguide.net E102 is

Tartrazine appears to cause the most allergic and/or intolerance reactions of all the azo dyes, particularly amongst those with an aspirin intolerance and asthmatics. Other reactions can include migraine, blurred vision, itching, rhinitis and purple skin patches, (because of this more use is now being made of Annatto (E160b).

Two synthetic coloring agents that combine to make green. The manufacturer insisted if I put this product in direct sunlight for one week that the color would change in a manner consistent with chlorophyll coloring.
I hypothesize that at most the color may show some fading from its vibrant green to a less saturated green, but it won't change from green to feuille morte as would be expected with chlorophyll.
We shall see.
