It may be a problem with the motherboard, resulting in RGB lights can not switch to colors normally used.
Please contact this email address service@sunfounder.com, the after-sales team will send you a new motherboard replacement.

About RGB lights only showing white, maybe the motherboard batch is different, PWM support frequency is also different, we fix the software, and you update the software to see if it can work properly.
The update command is as follows:
cd ~/Pironman
git pull
sudo python3 install.py --no-dep
Finally, type sudo reboot to reboot.

I updated the new sofware then rebot and …
All is OK
i tested colors red, green blue switch on/off, it is now OK
Thank you for your quick answer
Can you tell the service that my case is resolve

It is a PWM issue of Raspberry Pi. We set the PWM frequency higher so that the PWM input by the Raspberry Pi is within the working range of the LED.
