This genre was forgotten until 2023. It was re-invented, when @Jubale casually asked what would happen if [Akari] had lights of varied colours. @Jolson elaborated on this idea by suggesting the use of colour targets, included mixed secondary colours. The ´´hex´´ variant then appeared naturally as a way to allow three-colour mixing (white target), following the [RGB Loop] convention. ## [akari-rgb] puzzles | :info: **Setting tip**: the following uniqueness deduction may be undesired: ||if a cell sees no target color clues, any lightbulb can be placed there - so if the puzzle is unique, no lightbulb will|| | //by @EliDoris// ### site.author

Thanks @Plostoni, @jubale, @wisteria, @WesselStrijkstra, @Matze, @EliDoris for feedback. **2023-10-09** @Wisteria made the first Akari RGB (11x11) after the example puzzle - thank you! **2023-10-10** Assorted changes changes: RGB pencilmarks added (@Malrog), satisfied clues became grayed out instead (@dohz), added a panel clarifying that lights can be on targets (@mopp), hidden target under walls no longer allowed (@Wisteria), aux marks are hidden by LOS (@Plostoni). **2023-10-11** Big RGB Akari redesign with @EliDoris: colours were adjusted using the LAB colour space, targets moved to corner so they are visible at all times; textures added to preserve colourblind-friendliness. **2023-10-12** Added "unknown" lights, suggested by @Wisteria (who shared one extra puzzle)! Textures swapped by small corner letters, and lit tiles became slightly translucent. Added one extra panel and clarified another (@tenth, @dohz, @Xsheep). **2023-10-12** Fixed the dragging bug reported by @Blaz and @Seren (which might have affected others as well) **2023-10-13** Added the hex variant, following the same convention as [RGB Loop]. @Wisteria shared the "Glider Gun" puzzle! **2023-10-14** @Carrick22 shared a fantastic set of 3 puzzles, and @Wisteria shared the largest puzzle, "Prismarine"! **2023-10-17** Added set of three puzzles by @EliDoris, two of them hexagonal! **2023-10-18** The actual first Hex Akari (RGB) by @TheBookWyrm, was added today - thank you! Loading bug fixed (@Karoo) **2023-10-19** After pondering ideas by @TheBookWyrm, @Wisteria and @Malrog, placeable laser lines were tentatively added. Thansk to @EliDoris for sparking the discussion. **2023-10-25** Thanks to @EricFox for [live-solving Akari (RGB) on Cracking The Cryptic|https://www.youtube.com/watch?v=kUT-PK4yeVQ]! **2023-10-26** Three additional puzzles by @Wisteria and @EliDoris were added, including the ´´antiking´´ variant! Difficulties revised. **2023-10-26** Well-lit target visibility increased, as suggested by @Jubale. Thank you! **2023-11-23** Minor regression fixed (the line and sketch tools had been made available by accident) **2023-12-02** Variant-of-variant ´´antiking-equal´´ added with a huge puzzle by @PinkHoodie - thank you! **2023-12-05** A click area misalignment detected by @Wisteria, causing some lightbulbs to be incorrectly placed (or not at all), was fixed. **2023-12-06** Lightbulbs can no longer be placed on absent tiles (a regression detected by @Wisteria) **2023-12-19** A template loading regression reported by @PinkHoodie and @calica on hex grids was corrected **2024-01-24** :::puzzletters @Wisteria's puzzles //City of Gold//, //Gemstone// and //Beehive// were added - thank you! **2024-03-21** :::puzzletters @PinkHoodie sent a second ´´antiking-unequal´´ variant puzzle, showcasing an interesting deduction in a compact 9x9. **2024-03-27** ´´knapp-daneben´´ now works in [Akari RGB], a suggestion by @Leeor **2024-03-31** Local variant ´´knapp-daneben-hue´´, created by @Leeor was added to [Akari RGB], alongside two puzzles! **2024-05-18** A bonus puzzle of the [Akari Dice Series|Akari#DiceSeries] was shared by @JoeLangstaff. **2024-10-24** Thanks to @laclale for detecting a setting error in one of the puzzles (target over black), corrected. **2024-11-25** Former local variant antiking-equal renamed just ´´antiking´´ (like the global variant) whereas former variant ´´antiking´´ renamed ´´antiking-any´´ (local variant). This aligns the behaviour with that across other genres. **2024-11-25** Thanks to @PinkHoodie for making the variant panels ´´antiking´´,´´antiking-any´´,´´antiknight´´,´´antiknight-any´´ **2024-11-27** A visual regression on hex grids (checkered triangular tiles) that had been tolerated for some time is now corrected. **2024-12-06** :::puzzletters @PinkHoodie set 3 [akari-rgb] puzzles using variants ´´antiking-any,antiknight´´; ´´antiking,antiknight-any´´ and ´´knapp-daneben-hue´´ crafted 3 [akari-rgb] (classic) puzzles, , including a 12x1. **2024-12-09** Genre authorship was updated today, considering the info sent by @PinkHoodie and prior research by @JoeLangstaff **2024-12-28** :::puzzletters @PinkHoodie shared 1 [akari-rgb] (classic) puzzle - kiitos!
