Wouldn't the ocean change to brown too if you changed rivers to brown?

Sounds like you would need to work a little with the map_h in river valleys. Have you tried using the plates?

Sorry, I thought you were talking about just altering the colour of FF's plates. I didn't realize you were referring to the in-game rivers.

I think they can be made brown. The game itself makes them brown at certain greyscale values which it interprets as being "shallow". You would have to make sure you use this value on map_t and map_c and not the value for "deeper" rivers.

I tested them but haven't used any yet. I guess I should flatten the valleys in Map_H that would help.

Does anyone know which greyscale value could change the shallow river color to brown? Which Load line is changed?
