What Hacker News says

Anyone here using Penumbra? https://github.com/nealmckee/penumbra > »Penumbra is a mathematically balanced colour scheme constructed in a perceptually uniform colour space with base colours inspired by the shades of colour occurring in nature due to the light of the sun and the sky. It cleanly separates the perceptual properties of colours while optimally utilizing the available colour space of typical displays.« It was mentioned here ~3 months ago: https://news.ycombinator.com/item?id=32348461
In Solarized
> The search for a theme led me to Solarized by Ethan Schoonover, which I was ultimately not satisfied with but inspired me to try and improve on its ideas. https://github.com/nealmckee/penumbra#acknowledgments Which reminds me, of https://github.com/jan-warchol/selenized/blob/master/whats-w... Selenized is another theme which aims to improve on Solarized. https://github.com/jan-warchol/selenized/blob/master/feature... https://github.com/jan-warchol/selenized/blob/master/balanci... Wonder how they compare.
In Show HN: Penumbra, a perceptually optimized color palette based on natural light
At first, your color palette made a very good first impression to me. > I’m claiming it is an improvement in terms of usability, simply because Solarised wasn’t designed with these properties in mind. Are you sure about that? On [1] and [2] the creator of Solarized describes why he choose low contrast and specific hue differences, representable in CIELAB. That sounds rather similar to your first three points in [3]. Even if the approaches have some similarities, it does doesn't denigrate your work. Thanks for continuing this line of work. And I am looking forward to test Penumbra in comparison to Solarized.

Show HN: Penumbra, a perceptually optimized color palette based on natural light

For this palette, I used recent advances in color science, which made perceptual design more accessible, to choose a set of colors (mainly for syntax highlighting) that have uniform luminance for less visually uneven, fluidly readable code, but at the same time maximally distinguishable hue and chroma. The background colors are based on natural (sun-)light and shade for a more pleasing look than equally neutral greys. For much more detailed info, including the construction, check out the repository. There’s also already a (bare-bones) VSCode extension, linked in the repository, but it could admittedly use more informed distribution of colors over tokens, language specific highlighting and perhaps more opinionated use in UI elements.
