adjust pixel color depth

[maho24at]

Hi,

I got 6 panels each 64x64px to run on an ESP32 S3 N32R8

I'm using virtual display because I have 2 rows and 3 colums, and on top I would like to use double buffer, but the PSRAM is not large enough, so I had a look into the debug and researched here a little bit and I would like to know if reducing the color depth would solve my problem? (ecxel sheet says so...)

how can I change the color depth?

my project is just a huge clock with no fancy graphics, I'm using only red blue green yellow orange white and black, and I also dont need a high refresh rate, basically 2fps would be enough!

I need double buffer because the clock is on a race track and flickering is the worse thing if you go by a display pretty quick,
