Frog variants in all kinds of oceans are always temperate (orange), not cold (green) or warm (white), unlike in bedrock edition.
Temperature | (Deep) Frozen Ocean | (Deep) Cold Ocean | (Deep) Ocean | (Deep) Lukewarm Ocean | Warm Ocean |
|---|---|---|---|---|---|
Java | Cold | Temperate | Temperate | Temperate | Warm |
Bedrock | Cold | Cold | Temperate | Warm | Warm |
Bedrock's behavior makes more sense, as the biome names even state it's cold or warm.
Can confirm.
