These are all Minecraft bugs I cannot fix.
This is how the game works.
Please do not report these issues.
Custom liquid color mixed with water and vice versa
Custom liquids are not totally colored sometimes, some parts still have vanilla water color.
This is a limitation of how the game works. I cannot fix this.
Technical reason
Minecraft stores biomes of a chunk in an int[1024]. 16x16x256=65536, that's way more than 1024. This means that it stores it in some kind of blobs (not sure myself which size they are), so changing specific blocks is sadly not possible. The colours also fade between biomes, so changing small "blobs" always looks weird and the blocks won't have the full colour.
I cannot see liquid color at all, even by placing it in a different location
You have to set the biome blend to 5x5 or lower.
Bad
Good
Liquids on top of each other show the same color
You can do that only if your client is 1.18.1 or greater.
Old clients cannot see these colors correctly, it's a limitation of the game.
If you place normal water (or if it's naturally generated) on the top or on the bottom of a custom liquid you will see it will have the custom liquid color.
This is a Minecraft bug I cannot fix.
Bad - 1.17.1 and lower
Good - 1.18.1 and greater
Liquids do not spread like water!
It's working as intended to avoid lag and glitches.
Use multiple liquid buckets to place a wider liquid area.
