- The arils contain a smaller seed in a juicier pulp which varies from a light pink to a deep red in color.
- The arils contain a smaller seed in a juicier pulp which varies from light pink to deep red.
In first sentence, the indefinite articles before "light pink" "and "deep red" belong to the words "pink" and "red", signaling that they are not adjectives but nouns. "In color" looks redundant: if a pulp is red, it is necessarily "in color."
Is there a difference in meaning between the two sentences, or is it just a stylistic thing?
