Ooohh… I haven't looked into water temperatures yet. I seem to recall reading that temperatures are stored in a separate layer, kind of like biomes. I'll have to investigate!
FWIW, I have compiled a local build of minutor from their in-development 1.13 source code since they don't have an official release. Let my zip up my latest build of the Mac app if you want to take it for a spin…

Here you go! I haven't tested this on any system beside my own, but hopefully it "just works".

edit: NOPE! I was wrong, which in this case is good. Temperature-specific oceans got whole-new biome IDs, which makes this super easy to support!
Code:
warm_ocean = 44
lukewarm_ocean = 45
cold_ocean = 46
deep_warm_ocean = 47
deep_lukewarm_ocean = 48
deep_cold_ocean = 49
deep_frozen_ocean = 50
edit2: And furthermore, here are the hex color codes I'm using for those biomes:
Code:
44: "0000ac",
45: "000090",
46: "202070",
47: "000050",
48: "000040",
49: "202038",
50: "404090",
