Управляем компьютерной RGB подсветкой без пк

Компьютерная ргб подсветка несет краски в наш мир, и конечно же пачку тяжеловесного софта который отнимает драгоценную память и циклы процессора. Но под капотом большинства аксессуаров с ргб подсветкой прячутся светодиоды с чипом WS2812 который легко управляется с простого микроконтроллера. О простом способе подключения таких девайсов без пк я расскажу далее в статье.

It's time to put to rest #hex and #rgb() / #rgba() colours in #CSS and embrace the future: #oklch() and #oklab()

* oklch() model: https://caniuse.com/?search=oklch%28%29
* oklab(): https://caniuse.com/?search=oklab%28%29

I'm not sure why we still need to add/support lch() and lab() since the ‘okay’ version is the ‘fixed’ version… which is better. Then again, I'm not a #colour expert, hence I can't think of a reason. (Can someone enlighten us, mortals? Thank you!)

Since oklch(), oklab(), lch(), and lab() are still not widely supported (yet), and many end-users are still using an old version of browsers without support, there is #hwb().

As you can see from https://caniuse.com/?search=hwb%28%29 hwb() is widely supported already. The only browsers still without hwb() support are niche browsers, mainly from China (they don't even support rgb() according to #CanIUse).

* Base #color model: hwb()
* To be future proof: oklch() or oklab()

What I'm more excited about is the #RelativeColor feature from #CSSColor5, but that's for another day.
