Signal Flags

The Burning Ship map z -> (|Re z| + i|Im z|)^2 + c iterated over the parameter plane at an ultra-zoom on the mast tip of a western armada ship, centred at c = -1.94207120 - 0.00760600i with the window 1.0e-4 wide. Hue cycles with the smooth escape count at a period of 2.0, set against the roughly 7 units of count the legible glow actually spans. Chroma fades wherever the local count gradient exceeds 11 per pixel, so the sub-pixel bands ride a white core instead of aliasing.
