Colour Settings for Inky pHAT

My pwnagotchi is displaying info on his Pimoroni Inky pHAT 3-Colour display. But there don’t seem to be any colours. Is this correct despite there being red and fastAndFurious options as described in default.yml?

I am using the following in config.yml:

ui:
    display:
        type: 'inky'
        color: 'red'
