Vizard Agent

How to make a set of YouTube thumbnails in your brand colours

Last updated 2026-10-10 · 2 min read

Give Vizard Agent your exact palette and the headlines you need. Vizard Agent checks which of your brand typefaces are available and finds the closest matches, generates the artwork for each thumbnail, composes the headline, rebalances the layout, and iterates the details until the image reads at a glance.

What do you type into Vizard Agent?

Give the hex codes rather than describing the colours. Vizard Agent enforces an exact palette when it has exact values, and "navy and pink" produces something in the right family that will not sit alongside your existing thumbnails. Write the headlines yourself and keep them short, because they are the video's promise rather than its description.

Prompt

Make a series of [1280x720] YouTube thumbnails for [the channel]. Brand palette, strictly: [#0a053e navy, #ff0063 pink, #4ac7e5 cyan, cream]. Headlines: [one per thumbnail]. They need to match each other as a set.

What does Vizard Agent actually do?

A thumbnail has to work at the size of a postage stamp, with a headline somebody reads in half a second. Much of the job is iteration. An arrow that crosses the headline makes both unreadable at small size, so Vizard Agent places, checks and moves the details until the picture and the text both work. In the session behind this article it:

When does this not work well?

A thumbnail is a very small canvas, and much of what you might want doesn't survive being shrunk. Four or five words is the practical limit for a headline, detailed artwork disappears until only shapes read, and a person in the background becomes a smudge. If your exact brand font is unavailable, the nearest match is close, not identical.

Common questions

Can Vizard Agent match my exact brand colours? Yes, given hex codes. Vizard Agent treats colour names as a family rather than a value.

What if my brand font is not available? Vizard Agent finds the closest available match and tells you which it used.

Why move the arrow three times? It has to point at the right thing without crossing the headline, and those two pull against each other. Vizard Agent checked each placement.
