Hello! just popped over from the Autumn thread to answer Aque's question about blue Springs. Apologies for the long answer...
Basically, a Blue Spring is still definitely a 'warm' skin tone, it just isn't as warm as, say, a paintbox or a golden spring. So it's cooler than most Springs, but definitely not cool, if that makes sense. A Blue Spring is most likely to be confused with a Winter, as they are usually very 'Bright', and is generally seen as a leaning-towards-Winter season (but don't let that trick you into thinking you're cool if you are a Blue Spring). A Pastel Spring can be (but isn't always) a less-warm Spring who might look like a Summer.
In each of the HoC seasons, there is a category or two for someone who is less warm or less cool - I am a Blue Autumn, for instance. I look exactly like a Winter, any online analysis makes me a Winter, and my skin tone isn't very warm, but it is warm. Fuchsia/magenta/cobalt blue/chinese blue/black all make me look like a walking corpse.
It is hard to equate that with CMB or other companies, as I know for a fact that CMB's equivalent of a Bright Spring palette contains a few blue based colours, and also some of what i would call Autumn colours (i.e. quite rich/muted). I have one of these palettes sat in front of me as I type - I was incorrectly analysed as a Clear and Warm (Bright/Blue Spring equivalent) by CMB, but could immediately see that lots of the colours really didn't work on me, and IMO that's because they draw from too many seasons and I don't think they have an equivalent of a Blue Autumn, which is probably why I was analysed wrongly - there was literally nowhere to put me in their system, as far as I can tell. I don't think the CMB deep autumn palette (closest equivalent to a Blue Autumn) has any of my best colours - royal purple, petrol, geranium, forest green etc.
While I'm here, Fooogle the style day covers scale of patterns (big, medium or small or somewhere in between) and also what type of patterns (angular, geometric, regular dot/stripe type patterns, more floral/flowy patterns etc etc). Among about a million other things, but pattern issues would definitely be clear after style day. It's to do not only with the physical scale and body architecture of the person, but also their presence/personality/attitudes etc.
