Fix low-contrast brand colors

When a brand color is too light to read on, your text disappears. PostPop checks every pairing and suggests a readable fix — so posts stay legible, on brand.

Every brand has that one color that looks great on a wall and vanishes on a screen — a soft mint, a pale yellow, a light grey. Put text in it on a white slide and half your audience can’t read it. They don’t squint; they scroll.

PostPop measures it for you. It checks each color against the backgrounds text actually sits on, flags anything below the readable line, and offers a fix that keeps you on brand and legible — no color theory required.

Do it in 5 steps

1

Open your brand kit

In Brands, open the kit you want to check. Contrast lives right alongside your colors, fonts and logo.

Studio → Brands → your kit → Colors

PostPop checks contrast

It tests each color against the backgrounds your text sits on — white slides, dark slides, accent panels — and rates every pairing.

See what fails

A plain readout: which pairing falls short and by how much — the ratio and whether it clears AA. No guessing which color is the problem.

Apply the suggested fix

Accept PostPop’s readable pairing in one tap — a darker text shade, a swapped background, or using the color as an accent instead of text.

Fix: use mint as background → 5.6:1 · AA ✓

What the check gives you

Not just a red flag — the number, the fix, and the rule behind it. Tap through.

Every pairing, rated

Each brand color scored as text on the backgrounds it’ll sit on — with the ratio and the AA/AAA level, so you see exactly what’s safe.

A readable pairing, suggested

The flagged color isn’t dropped — it’s re-cast. Here mint moves from text to background, and the same slide becomes readable.

The line it checks against

PostPop targets WCAG AA by default — the same bar accessible sites use — so a post reads on any phone, in any light.

AABody text≥ 4.5 : 1
AALarge text≥ 3 : 1
AAUI & graphics≥ 3 : 1
AAABody (strict)≥ 7 : 1
TIP
Pale colors are backgrounds, not text. A soft yellow or mint sings as a slide background with dark text on top — it just can’t carry text on white. Let PostPop assign the role and you keep the color without losing the reader.

Why it’s worth the check

Same words, same brand color. One slide gets read; one gets scrolled past.

Common questions

What contrast level does PostPop target?+
WCAG AA — at least 4.5:1 for body text and 3:1 for large text — so posts read on any screen, in any light.
Will it change my brand colors?+
No. Your palette stays exactly as it is. PostPop only changes which color carries text versus background, or suggests a readable shade for text.
Can I override a warning?+
Yes. If you accept a low-contrast pairing on purpose, keep it — the warning is guidance, not a lock.
Does it check every post?+
Yes. Once contrast rules are on, generated posts use readable pairings automatically — you don’t re-check each one.

On brand, and actually readable.
