Newest first.
Rewrote the generator and redrew the site around it.
The colours used to be a plain rotation of the base hue in HSL. That held up while the base stayed somewhere near orange and fell apart everywhere else: start from blue and red came out green. Each of the six colours now has a home hue and only leans towards the base. Each is also set to the same contrast against the background, where it used to get the same HSL lightness and blue ended up the one you squint at. The 42° step and its write-up went out with the rotation.
New: a light background, sliders for contrast and tint, six colours to start from, links that carry the palette, and exports for foot, WezTerm, Ghostty and Windows Terminal. The old saturation and lightness numbers do not map onto the new sliders, so a palette made before today will come out different.
Moved the site to another server. Nothing about the generator changed.
Bright row now trims saturation by 6 instead of keeping it flat. On an OLED panel the old bright yellow was painful; this is closer to what the normal row looks like at higher lightness.
Added the kitty export. It is just colorN lines, but copying them by hand from the Xresources block was getting silly.
Black and white slots stopped following the hue rotation — they now take the base hue with the saturation pulled down, which keeps the background from looking tinted at low lightness.
Hue step changed from 45° to 42°. Red and magenta were landing too close on a warm display; the writeup on the front page explains the reasoning.
First version put online. Xresources export only, no preview swatches.
