How it differs from its neighbours
The check mark says "done", the question mark points to help, and the warning triangle means "careful": a caution box in a manual, a failed field in a form, a notice about a risky setting. It is a signal, not decoration, so one per screen is usually enough.
What to look for in the file
The exclamation mark here is a hole, not white paint: on a coloured background the colour shows through it. Official safety signage expects yellow or red, so for real labels recolour the solid shape and keep the thick border proportions.
