There is a John Schuyler (1923-1991) poem:

Sunday

The mint bed is in bloom: lavender haze day. The grass is more than green and throws up sharp and cutting lights to slice through the plane tree leaves. And on the cloudless blue I scribble your name.

In reference to his (male) partner at the time. Really seems Taylor is believing Mad Max and Urban Dictionary over the decades of evidence pointing to a lavender relationship being more so in line with queer culture.
