Load Palette at Runtime?

[MasochisticGamer]

I'm aware of the ability to change a frame's palette (Using the NTSC NES palette for the game I'm working on) But is it possible to change the palette during runtime so that I could create a day to night transition without using the Colorize extension? (Trying to stay within the NES palette limitations)

I think not, but would be happy to be corrected

If you haven't already tried,
maybe you can achieve similar results playing with RGB coefficients of frame,
this can be done through "storyboard controls - frame - effect - set RGB coefficent"

Or, for nightfall, by lowering an additional "black" layer alpha transparency,
although it's a less elegant and "colored" solution...

Edit: both of these would however alter original NES palette capabilities
