In a "telo suno" I see rather "light/ a flow of sun shine", e.g. as in a fun love song:It is poetic and beautiful but very counter-intuitive. It sounds more like a "liquid gold" not a "blood"
telo suno li pana e seli
suno ni li weka e len
sina seli e mi, o meli
wile mi li suli e ken
* if someone may propose a melody, I guess, it will be very interesting.
