Are You a Colour Connoisseur? This Tricky Online Test Will Reveal All
Most of us reckon we’ve got a pretty good handle on colours, a skill we master as toddlers. But what if we told you there’s a new online test that could have you second-guessing your entire perception of the colour spectrum? Enter the ‘What’s My JND?’ test, a surprisingly challenging game designed to pinpoint your ability to distinguish between subtle colour variations.
The premise is simple: you’re presented with two colour blocks on your screen and asked to click on the invisible line that separates them. Easy, right? Well, the game’s creators explain that while it “starts easy,” it “does not stay easy.” As you progress through each round, the colours become progressively more similar, making the task of finding that dividing line a genuine test of your visual acuity.
The game typically runs for around 40 rounds. Your goal is to identify the smallest colour change you can perceive, known as your “Just Noticeable Difference” (JND). The average score among players hovers around 0.02. So, the burning question remains: can you do any better?
This intriguing digital challenge is the brainchild of software engineer Keith Cirkel. His motivation? To explore the question of “just how precise is precise enough” when it comes to displaying colours on digital screens.
To give it a go yourself, you can head over to the game’s website. Once there, simply tap or click the white button that reads ‘Let’s go’ to begin your colour-sorting adventure.
Navigating the Nuances of Colour
In the initial stages of ‘What’s My JND?’, the colour differences are quite pronounced. You might be presented with clear contrasts like grey and blue, brown and orange, or purple and blue. These early rounds serve as a gentle introduction, easing you into the gameplay.
However, as you advance, the game ramps up the difficulty significantly. The shades will begin to blur, becoming increasingly nuanced and demanding a sharper eye. What might have seemed like a single colour previously will now reveal subtle gradients that require careful observation to differentiate.
After each guess, the game provides immediate feedback, letting you know if you’ve hit the mark or if your perception was, as they put it, “wildly off.” This instant feedback loop is crucial for understanding where your strengths and weaknesses lie in colour discrimination.
Decoding Your JND Score
Upon completing the game, you’ll be presented with your JND score. This score isn’t just a number; it’s a reflection of your colour perception capabilities. The game then contextualises your performance by comparing it to the scores of other players.
If your score is on the lower end, don’t be too disheartened. The game offers a rather blunt but humorous message: “Rough. But look, I once failed a colour vision test because the room had fluorescent lighting. Environment matters. Try again in a dark room with your brightness cranked. Or don’t. I’m not your mum.” This highlights how external factors can influence our perception.
On the flip side, if you achieve a truly exceptional score, prepare for some high praise. A successful player might receive a message like: “Genuinely remarkable. You sailed past the theoretical human limit like it owed you money. I’d accuse you of cheating but I don’t actually how you’d cheat at this.” It’s a testament to an incredibly sharp eye for detail.
Beyond the Basic: Hard Mode and Player Reactions
For those who conquer the standard ‘What’s My JND?’ test and crave an even greater challenge, Keith Cirkel has also developed a “Hard Mode.” In this intensified version, you’re presented with a grid of nine squares. Eight of these squares are identical in colour, while one is subtly different. Your task is to locate and identify this solitary outlier.
The game has quickly gained traction, with players enthusiastically sharing their results and experiences on social media platforms like X. Many are fascinated by the insights it provides into their own colour perception.
One user shared their delight, tweeting: “This is great fun. How good is your colour perception? What are the finest shades you can distinguish? Apparently I’m a bit special.”
Another player admitted to struggling, noting: “Some were just completely uniform to me. I had no idea. Had to keep tilting my screen all ways to try to spot a border but still ended up guessing.”
In a lighter vein, one participant humorously commented: “Not bad considering I’m colourblind.” This remark underscores the diverse range of visual experiences people have and the varying degrees of challenge the test presents. The ‘What’s My JND?’ test is more than just a game; it’s a fascinating exploration of human perception and the subtle complexities of the world around us.
