If your skin is ruddy (red-like) tones then you want to pick a foundation that has warm undertones in it to counteract your redness.
Philosophers have often argued that possession of a common property (like redness), together with certain linguistic conventions, explains why general terms apply to the things that they do.
LL-37 induces interleukin-8 (IL-8) secretion by human keratinocytes, and injection of LL-37 into mouse skin recapitulates rosacea-like redness and PMN infiltration [3].
To the extent that a property like redness allows us to count red things, it is because we are relying on the umbrella count noun 'thing' to help with the count.
Clinical side effects like redness, swelling, desquamation, and pimples, and sensory effects like burning, tense feeling, and itching were recorded by the test subjects.
Sortal properties are naturally contrasted with characterizing properties, typically expressed by adjectives like 'red' and 'triangular.' Characterizing properties, like redness and triangularity, do not divide the world up into a definite number of things.
Red is normally an adjective, but when an adjective is used in an abstract sense to mean something like redness, then we can use it in noun form: I want red on this wall here, an interior designer might say.
In connection with properties, the standard immanent-realist view is that properties like redness exist only in the physical world, in particular, in actual red things, as nonspatial parts or aspects of those things (this view traces back to Aristotle; in contemporary times, it has been defended by Armstrong (1978)).
