Soft monochrome, sealed worlds
The Bene Tleilax let the Imperium believe exactly what the Imperium wishes to believe: that they are repellent, and simple, and for sale. Their worlds are sealed; their words are bred in pairs; their real faith is never spoken with outsiders. The palette works the same way. It is the series' other bones theme, but the opposite pole from Harkonnen: where the black sun renders the world in hard monochrome — maximum contrast, neutral ink, spectacle — the vats render it soft: minimum contrast, and everything steeped faintly green, as if the whole screen were read through axlotl fluid. Keywords still land by weight, in waxBone bold. Comments are a whisper, the faintest in the series, present only if you lean in. And the one saturated thing in all that murk is gholaRed: the single drop of blood in the tank.
Then the palette does what Tleilaxu do: it grows copies. Every accent has its ghola — a dim twin, the same hue decanted paler. Function definitions wear scalpel, while every call site wears its ghola, because each invocation is the declaration grown again. Your own types wear sisterhoodViolet, but the mass-produced primitives wear the violet's ghola. Originals declare; gholas repeat. As for the violet itself, it keeps the series name here as everywhere, whatever the Masheikh mutter about powindah witches. Some of what they mutter is recorded below, in ink the vats prefer you not notice. Select the blank spaces.
