You have seen the infographic. Blue means trust, red means passion, green means growth, purple means royalty. It gets shared every week, and it is the single most overrated idea in logo design. Not because color does not matter. Because it matters for a completely different reason than the infographic says.
The problem with the meaning chart
If blue reliably manufactured trust, banks using blue would be trusted, which is a sentence you can test against your own feelings. Color-emotion associations are real but weak, heavily context-dependent, and culturally variable. Red is appetite in one aisle, danger in another, and a national flag in a third. The chart flattens all of that into astrology for brands.
What color actually does
Color's real job in a logo is identification, and identification is relative. The question is never "what does orange mean?" The question is "who else in my market is orange?" Color works as a brand asset when it is distinctive within the category, applied with total consistency, and given time to accrete memory.
- In a sea of banking blue, a challenger in near-anything-else gets remembered for free.
- In delivery apps, the market is a full crayon box, so color alone cannot carry identification and shape has to do the work.
- Category conventions are real but breakable: violating them costs a little comprehension and buys a lot of visibility. That trade should be made on purpose, not by template default.
Consistency beats meaning
A mediocre color used identically everywhere outperforms a perfect color used loosely. This is why "three different blues in the wild" shows up on so many of our report cards: each variation splits the memory deposit across separate accounts. Pick the value, write down the exact codes for screen and print, and defend them like a password.
