Issue with differentiating layers when using netclasses colouring

Phils Lab board

Hello. I'm following "PhilsLab's tutorial for KiCAD 9"(very popular video) where he uses netclasses colouring. I want to use them because he said it is easier to understand and generally a good practice to use net class colouring. But as you can see here it makes it difficult to distinguish what signals are on which layer. What are your thoughts on netclasses colouring. Would you say Phils Lab is wrong?

Grade my PCB

Hello. I come forward and ask for the opinion of my first PCB design. Its heavily relied on PhilsLab PCB tutorial for KiCAD 6. Im connecting to 4 devices via SPI, I2C, I2S and of course serial debug. The PCB has:

-AMS1117-3.3 (max power supply 1A)

-STM32F103RCTx - (Max 150mA)

-AMOLED 0,96″ 128x64px via I2C- (Max ~3mA)

-MicroSD via SPI (max 170mA)

-MAX98357A I2S (max 1A) - i know this is too much but i guess i will be limiting so it doesn't take so much power.

-some 4 ohm buzzer/speaker.

So i have around ~0.4A already consumed by peak current of STM and MicroSD interface. I will have around 0.6A for the audio.
