Logo Lab FAQ
Why is 16px the test that matters?
It is the browser tab — the size your mark lives at most hours of its life. Wordmarks and fine detail die there; shapes survive. Many identity projects meet this truth for the first time in this lab, which is cheaper than after the rebrand.
My logo fails dark mode — options?
The standard fixes: a keyline stroke, a contained shape (badge/tile) behind the mark, or an alternate dark-mode variant. What doesn’t work is hoping — the second row already showed you.
