Astrid, I read a few more descriptions of the summers and thought about the colours of the palette that seem to work best for me. To tell the truth, I think I am somewhere *in between* soft and true. I may look nearer to "soft" when my skin is a bit tanned (so more neutral) and a bit nearer to "true" when my skin is not tanned.
I remembered the colour consultant's confusion that I could wear darker colours better than she had expected. It turns out that is a common characteristic in "soft" summers vs. "true" summers. Also, what really looks worst on me are super bright or clear colours -- I just disappear. So that seemed like another clue.
But mostly it had to do with how very well I wear taupe. That is not a colour that works quite as well on a "true" summer.
On the other hand, I look awful in the light coral that most "soft" summers are supposed to be able to wear, horrid in those light yellows, and I really can't handle much warmth at all, except for true red (sometimes). Plus, one of my best colours is that soft fuchsia, which "true" summers seem to wear best.
So, like you, I'm happy to pick and choose between them, just generally keeping the soft - shading -into true summer in mind. I guess in the end if we focus on cool, mid-toned colours with greys, taupes, navy, or soft white as neutrals, we'll be all right.
