uW Translation Notes:

Note 1 topic: figures-of-speech / metonymy

θώρακας πυρίνους, καὶ ὑακινθίνους, καὶ θειώδεις

breastplates fiery (Some words not found in SR-GNT: Καί οὕτως εἶδον τούς ἵππους ἐν τῇ ὁράσει καί τούς καθημένους ἐπʼ αὐτῶν ἔχοντας θώρακας πυρίνους καί ὑακινθίνους καί θειώδεις καί αἱ κεφαλαί τῶν ἵππων ὡς κεφαλαί λεόντων καί ἐκ τῶν στομάτων αὐτῶν ἐκπορεύεται πῦρ καί καπνός καί θεῖον)

John is describing the colors of the breastplates by association with other things that are those colors. If it would be helpful in your language, you could use objects from your own culture that are these colors or express the meaning plainly. See, for example, how you translated the word “fiery” in [6:3](../06/03.md). Alternate translation: [breastplates that were fiery red, hyacinth blue, and sulfur yellow] or [bright red, dark blue, and brilliant yellow breastplates]

Note 2 topic: translate-unknown

ὑακινθίνους

hyacinthine

A hyacinth is a plant in the lily family that has dark blue flowers on spikes. If your readers would not be familiar with what a hyacinth is, in your translation you could use the name of a plant or other object in your culture that is the same color as hyacinth flowers, or you could use a general expression. Alternate translation: [dark blue]
