This - particularly the bit I put in bold.If you're interested in modern television shows, watch modern television shows. If you want to know what television series used to look like, watch the old stuff. But trying to change the old stuff so that it's more acceptable to modern sensibilities is a colossal waste of time and energy.
To each their own and all, but colourisation is something I've never seen the point of. The few attempts I've seen have looked artificial and...well, crappy. Wasting time and resources to try to appeal to those people who think anything made in B&W isn't worth watching is ridiculous. If they're unwilling or unable to appreciate B&W TV shows / movies / whatever as they were made, that's their choice. Nothing appeals to everyone and trying to change it so that it might / does appeal to everyone is pointless.
So no - no colourisation for classic Who.
