Summary

A grammar-rule slide showing how to treat feature names as singular: the rule on the left, and four stacked serif example sentences on the right, two labeled DO and two DON'T, with the key verb colored teal (correct) or red (wrong).

Visual description

Cream background. The left column has a teal "WRITING GUIDELINES" eyebrow, a two-line navy serif heading ("Treat all top-level features as singular"), and a short gray sans rule. The right two-thirds is a tall bordered panel of four rows split by hairlines; each row carries a small teal "DO" or red "DON'T" label and a large navy serif sentence, with the contrasting word set in italic and colored teal ("Calls keeps," "Messages encourages") or red ("Calls keep," "Messages encourage"). The vertical "Brand Guidelines" label and blue Spark symbol sit at the left edge and bottom-left.

Key takeaway

Coloring just the single word that makes a sentence right or wrong (teal versus red, italicized) focuses attention on the exact decision point, while the rest of the sentence stays neutral navy. The paired DO/DON'T rows make the same sentence comparable line for line.

Reuse notes

Excellent for grammar, capitalization, or phrasing rules where the difference is one word. The color-on-keyword technique only works if the contrast words are short and obvious; for longer differences, fall back to bold or underline.
