Who makes Huekle

Huekle is built and maintained by Lajos Toldi, a qualified educator (MA in teaching) and PhD candidate in adaptive intelligent tutoring systems at AI24EduLabs, a research lab in the AI24Labs portfolio. That background shapes the whole approach: Huekle treats color sense as a skill you can practise directly, and its games are designed as small, adaptive daily exercises for the eye. Lajos designs the games and the measurement approach, and writes and edits the guides. The pedagogy and the practice method are his own work; claims about color and perception science are checked against authoritative sources and cited on each page — see our editorial policy for how sources are chosen and how AI-assisted drafting is used and reviewed. Huekle stays free, collects no student data, and is supported by optional passes and unobtrusive ads.

Huekle is one of three perception-training hubs from AI24EduLabs, alongside Chronkle (tempo) and Hearkle (pitch); the lab also builds AI24Tutors. AI24EduLabs is part of AI24Labs, together with AI24MediLabs and AI24EcoLabs.

What I work on

All of it, honestly. I design and build the daily games, from the rules down to the colors and the scoring. I write the guides in the Learn section, and I run the measurement approach that turns each game into a rough read on your color perception. When something feels off in a game, I'm the one who plays it a hundred times to find out why. There's no content team behind the curtain. It's one person, which keeps the whole thing consistent and keeps me accountable for it.

How to reach me

Email is the way: hello@huekle.com. I read what comes in, and I'm glad to hear about a bug, a confusing sentence, or a game idea. One thing to note: Huekle has no user accounts and no logins, and nothing you do in a game leaves your device. So if you write to me, I only know what you choose to tell me. There's no profile or history for me to look up on my end.

How the content is made

If you want to know how the guides get written and checked, or how a claim earns its place on the page, the editorial policy lays that out. And if you're curious what a game's score actually means, and what it doesn't, the methodology page explains how the measurements work and where they stop. I'd rather you understand the limits up front than trust a number that was never meant to be clinical.

Why this exists

Teaching taught me that people improve at what they get to practise on a regular schedule, and that a small daily rep beats a rare heroic session. Color sense is a skill almost nobody practises on purpose, even though it sits underneath design, photography, art, and plenty else. Huekle is my attempt to make that practice easy to reach: open the page, play a short game, and get a little feedback on where your eye landed today. Come back tomorrow and watch the trend. That's the whole idea, and it's free because it should be.
