Does colour psychology actually work?
Colours carry associations, but popular claims about them are overstated. You will often read that blue “creates trust” or red “increases appetite”. Research on colour and behaviour is mixed, effects depend heavily on context, and many figures that circulate online have no traceable source.
Treat associations as cultural tendencies that can help or hinder, not as levers that make people buy. What is reliably useful is more practical: colour is one of the fastest ways people recognise a brand, a distinctive colour is easier to remember than a common one, and a colour that clashes with what customers expect from a category can make a business feel out of place.
What do colours mean in India and Kerala?
Colour meanings are learned, so they vary by culture, religion, region and generation. Indian audiences bring associations that global colour guides often miss. The table lists common tendencies, not rules; your own customers may read colours differently.
| Colour | Common associations | Watch out for |
|---|---|---|
| Red | Auspiciousness, weddings, energy, urgency; widely used for sales and offers | Strong political associations, especially in Kerala; can feel aggressive in healthcare or finance |
| Saffron and orange | Spirituality, devotion, warmth, festivity | Religious and political connotations; poor contrast with white text |
| Yellow and turmeric | Auspicious beginnings, festivals, haldi ceremonies, cheerfulness | Hard to read as text on white; can look cheap when over-saturated |
| Green | Nature, agriculture, health, freshness, prosperity; significant in Islam | Political associations in Kerala; crowded among pharmacy and organic brands |
| Blue | Calm, reliability, technology, corporate seriousness | Very common in banking and software, so harder to stand out |
| White and off-white | Purity and simplicity; in Kerala, the kasavu off-white and gold of Onam and weddings | In some Hindu traditions, white is associated with mourning |
| Black | Premium, luxury, modern; worn by many Sabarimala pilgrims | Considered inauspicious for celebrations in some traditional contexts |
| Gold | Prosperity, jewellery, festivals, premium quality | Overused in jewellery and textiles; prints flat without special inks |
Kerala adds its own layer. The off-white and gold of the kasavu mundu and saree is so closely tied to Onam, weddings and tradition that it reads as heritage and quality to many Malayali audiences. Red and green, meanwhile, are strongly linked with political parties, so a predominantly red or green palette should be a deliberate choice rather than an accident.
How do you choose a brand colour palette?
- Start from positioning. Write three personality traits (for example precise, calm, modern) and reject colours that contradict them.
- Map your competitors. Collect the logos of 10–15 competitors and note their dominant colours. If most of your category is blue, a different primary colour is the easiest way to be recognised.
- Pick one primary colour. One dominant colour builds recognition faster than three equal ones.
- Add neutrals. Choose a dark text colour (a near-black or deep grey), a light background and one or two greys for borders and secondary text.
- Add one accent. Reserve it for buttons, highlights and offers so calls to action stand out.
- Define functional colours. Success green, warning amber and error red for websites and apps, kept distinct from brand colours where possible.
- Test in real use. Mock up a signboard, a WhatsApp profile picture, an invoice, a web page and a social post before approving anything.
When you test options with customers or staff, avoid asking which colour they like; personal favourites tell you little. Show two or three palettes applied to the same mock-ups and ask which looks like a business they would trust with the job, and which they would remember tomorrow.
Will your colours be readable and accessible?
A colour that looks good in a logo can fail badly as text. The Web Content Accessibility Guidelines (WCAG) set minimum contrast ratios between text and background: 4.5:1 for body text, and 3:1 for large text (about 24 px regular or 19 px bold) and for icons, input borders and other essential graphics. Good contrast also helps everyone reading a phone in bright sunlight.
Bright saffrons, yellows and reds are the usual problems. The ratios below were calculated with the WCAG formula; any free online contrast checker will give the same results for your own colour codes.
| Combination | Contrast ratio | Body text (4.5:1)? |
|---|---|---|
| White text on saffron #FF9933 | 2.1:1 | Fails |
| Near-black #1A1A1A text on saffron #FF9933 | 8.2:1 | Passes |
| White text on bright red #E53935 | 4.2:1 | Fails |
| White text on deeper red #C62828 | 5.6:1 | Passes |
| White text on green #138808 | 4.6:1 | Passes, narrowly |
| Grey #777777 text on white | 4.48:1 | Fails, just below |
The fix is rarely to abandon the brand colour. Keep the bright shade for large shapes and backgrounds, pair it with dark text, and add a deeper shade of the same hue for text links and buttons.
Design for colour vision deficiency too; red-green colour blindness is common, particularly among men. Never let colour alone carry meaning: pair red and green status colours with icons or labels, and check that charts still read in greyscale.
How many brand colours do you need?
Fewer than most businesses expect. A typical palette has one primary, one accent and three or four neutrals, plus functional colours for digital products. Specify each colour in every format you will use:
- HEX or RGB for websites, apps and social media
- CMYK for brochures, printed bills and packaging
- Pantone (spot colour) if you print in volume or need exact matches
- Paint or vinyl references for shopfronts and vehicles, matched by eye in daylight
A vivid screen colour can print dull, and flex banners, ACP signboards and newspaper ads all shift colour differently. Approve printed proofs, not just screen mock-ups.
What colour mistakes should you avoid?
- Copying the market leader’s colour, which makes you look like the cheaper alternative
- Choosing purely on personal preference or a single auspicious-colour recommendation, without checking competitors and legibility
- Setting body text in a pure, saturated brand colour
- Using many colours with no hierarchy, so nothing looks important
- Ignoring dark mode in apps, where bright brand colours can glare
- Letting shades drift between printers and designers because no colour codes were written down
Getting your palette right
A good palette is distinctive in your category, fits your positioning, respects your audience’s associations and passes contrast checks in real use. Colour is one part of a wider system; How to Design a Logo That Lasts: 10 Things to Consider explains why your mark should work in one colour before any palette is applied.
