"Tint Screen..." is driving me nuts! Options

[RoVee]

Hey guys!
I'm new here and I hope you can help me out with this problem I have atm.
I've read a few threads about tinting screens but they were not helpful for my particular problem.

Some explanation first:
The main character in my game can change day and night time by choice.
(When she goes to bed the first time, wakes up --> it's night.
When she goes to bed a second time, wakes up --> daylight again.)
That event repeats endlessly
and the tint applies to all maps (how it should be)

Now the problem:
I have one cave, where the tint is set to sepia as soon as she enters it.
(It's like a memory, so I'd really like it to be in sepia)
When she leaves the cave, the whole world is "sepia".
I only need it for this one map.
I know I can change the tint to "normal" when she leaves the cave.
BUT when it's night I can't let the auto process change into normal, you know what I mean?

How can I set the setting sepia tint for only one map so that it does not effect the other tint settings at all?
Same thing, when it's night I want it to be "normal tinted" in houses 'cause their is light y know... I just can't figure out how to do it.

Do you guys understand what I'm trying to say? xD
(sorry, english is not my native language)

I have a Parallel process in this cave, set to "tint sepia"
(It irritates me, because normally parallel processes only apply to the map they're on)


Sorry for the long post!
