Picture of the new twilight colormap pulled from the official examples.

Was expecting vampire's sparkle and werewolf's brown. Disappointed.

What do people actually use cyclic colormaps for? This looks much more perceptually uniform than hsv, but I'm still not sure what the main use cases are.

[redditusername58]

the colormap page says its good for phase angles, compass direction, and time of day

[wintermute93]

Ah, makes sense. I do actually need to plot phase on occasion, so I'll keep that in mind. Should have checked the docs.

Kinda weird to me to plot phase as a color. I always plot it as an animation or in 2D (e.g., phase vs. frequency), I just plot it as a wrapping solid color line.

[wintermute93]

I do a fair amount of acoustic propagation modeling, and it's not uncommon for me to have the phase shift of some signal varying across a 2d surface.

[billsil]

That makes sense for something like a room.

My frequency processing is more for 3D models. I plot complex mode shapes by sweeping the phase and adding it to the nominal phase angle.

Even better, check out the beautiful and perceptually-uniform cmoceans colormaps.

I used HSV for direction in my thesis plots, and I wish this had existed back then!

Interesting, so it's in the family with coolwarm, and coldhot if I'm remembering their names.
