I would not count on the color of the PCB and always verify it myself. In SPI, the CS pin is usually active low and can easily be measured with a DMM while idle: it should give 3.3 V. Note that measuring Vcc is not enough, because those faulty CH341As often have Vcc = 3.3 V and are marketed as 3.3V, but still use 5 V for the logic signals.
