The Dictionary needs the opposite: a frame in which <em>equal distance is equal perceived difference</em>, filled evenly, so that &quot;how far is this shade from that one&quot; has a single honest answer. That frame is the <strong>fine grid</strong>.</p> <h2 id="what-it-is">What it is</h2> <p>Take OKLab — the perceptual colour space the <a href="https://www.tartandictionary.org/posts/colours/">colour list</a> already uses — and simply fill it at one spacing in every direction:</p>https://www.tartandictionary.org/posts/six-colour-palette/Sat, 13 Jun 2026 00:00:00 +0000https://www.tartandictionary.org/posts/six-colour-palette/<p>The Dictionary names every pattern in a simplified six-colour vocabulary — white, black, red, green, yellow, blue, <em>&quot;the rest are shades of these six.&quot;</em> These are not screen primaries (tartans are not woven in <code>#FF0000</code>); they are representative cloth shades, chosen to <strong>maximise discrimination</strong> — to keep the colour distinctions that genuinely separate one tartan from another and throw the rest away. This post re-anchors those six onto the <a href="https://www.tartandictionary.org/posts/fine-grid/">fine grid</a> and re-runs the experiment that picked them.</p>
