I have a lip/cheek colour from Trinny London and like it. Dubious about the "colour match" service on her website though, it suggested colours that wouldn't look good on me at all. Some people claim that under "season" colour types anyone with black hair is automatically a "winter" - obviously a ridiculous idea since it covers a vast number of people, all of different races, skin tones, eye colours, etc. Maybe her algorithm is based on something like that idea
I like her wardrobe videos but agree she has a ton of clothes she can't possibly wear, and her choices aren't always flattering. She talks a lot about how her attitude has shifted since What Not To Wear (especially since a lot of her and Susannah's comments on the show are now considered sexist and "body shaming") but still seems to hold on to the idea that your clothes should always make you look thinner. That's fine, but looking slightly smaller in something does not mean it always looks good on you - the clunky shoes are a good example
