No you did not ... thanks
Did you have a problem with video calling colour an illusion?

I think I'm with SoS on this. 'physical colour', the physics of light and bus and visual system is a reliable discriminator of colour. The 'my red is like your red' spook inner mental world stuff is probably illusion. The bus isn't an illusion.
