New Designer Color Palettes for FastLED There’s a great web site for color designers called “cpt-city” (short for ‘color palette city’) that has page after page of pre-designed color palettes, for all kinds of things from art to science, maps to video games. Check it out: cpt-city Ever since FastL…

I try the “[PaletteKnife]” Link in Chrome. It contains this strange code: (javascript:(function(){s=document.createElement(%27script%27);s.type=%27text/javascript%27;s.src=%27http://fastled.io/tools/paletteknife/pk2.js?v=%27+parseInt(Math.random()*99999999);document.body.appendChild(s);%7D)();),

Yep. It’s a bookmarklet, not a plug-in. Drag the link itself to your bookmarks toolbar. There’s no download. The new bookmarklet is written in JavaScript. Once it’s “installed” in your bookmark bar, it will execute in your browser when click on it there.

I’m getting weird results. http://pastebin.com/3cDJ8i9J NOTE: line 44 of the conversion from the site

Hey @Jon_Burroughs : are you seeing that problem on any other URLs? (And thanks for the heads-up)

Hrm… looks like it might be the browser truncating a large text field. I have to admit that I tested ‘a lot’ with smaller palettes, and mostly stayed away from larger ones like that (that one has 254 control points). Next time I revise the PaletteKnife code I’ll add support for larger palettes as …

Hi! I’m a total FastLED newbie! Loving the palette knife demo code; thanks SO much! I think line 14 of the code needs to be updated for arduino 1.6.6 (same update was made in demoreel100) I made mine: #if defined(FASTLED_VERSION) && (FASTLED_VERSION < 3001000) //updated for Arduino V 1.6.6

Thank you! We need to get after all the samples this way, I think. (Or Arduino should fix their bug, but we can do our part, too.) Thanks again and enjoy the colors – please share your experiments and creations when you can!

Hi Mark! Nube FastLed question: how do I scale the 16/256 palette so it looks good on strips that aren’t evenly divisible by 16? I have 114 leds in a rectangle and I’m trying to get the start and ends of the animations to line up. Thanks!

Hey @Steve_Hurd , great question and I bet other folks are curious too. Would you do me a favor and start a new posting with your question (how do I make a palette work out evenly around a 114-pixel shape) and I’ll answer it there!
