Hey! :3 I’m working on a new blending mode for Krita. It blends nicely with existing semi-transparent strokes, but still allows applying color on top of existing colors. 🙂 It’s similar to Greater, but allows to layer colors using Opacity and Flow. Furthermore, it can be used to aid in simulating transparent mediums, for example Water Color wash like in the video, glazes with thicker “paints”, or in general digital painting if you control Opacity with a sensor. 😃 Here is a small comparison to `Normal` blending mode: https://www.youtube.com/embed/ZkFKSoauyUU?feature=oembed&wmode=opaque&list=PLBsW9BZAF-HzKARk-FoGGE83WRICALRdv Image comparison of `Normal`, `Greater`, `Wet Alpha` ![image](https://krita-artists.org/uploads/default/original/3X/9/7/97adc0199964f422471f7ffbbb3490fe9a6cc07d.jpeg) * * * You can follow my dev work on my: **Twitter - [https://twitter.com/SirPigeonz](https://twitter.com/SirPigeonz)** **YouTube - [Sir Pigeonz Art - YouTube](https://www.youtube.com/@sirpigeonzart1662)** ---

Awesome! Curious if my post inspired you a bit. [This post](https://krita-artists.org/t/all-brushes-used-on-designated-layer-uses-set-blend-mode/57392/3) The video you showed looks great. A little related. But I have an idea for how to organize/find blend modes faster, I love blend modes and even if we have many already I welcome any new ones that can find use. Might post a feature req. Krita stands out in the quantity of blend modes but is kind of lacking in way of switching between them quickly I used some Greater blend mode in this setup as well: > [@WaterColor Layer setup](https://krita-artists.org/t/watercolor-layer-setup/57273): > > THE .KRA file [https://icedrive.net/s/R5GzW3Pv1N4zxDiSF4Dg1hk5DThw](https://icedrive.net/s/R5GzW3Pv1N4zxDiSF4Dg1hk5DThw) if you don’t want to download file here is the layer blendmode setup: This uses clone layers, do not paint on them only the layer it clones from (edit I will post blend mode opacity later) the brush i use is using flat light on the brush blend mode, but only in grey scale. I find flat light kind of helps adds layering when painting over pass strokes. I used this br… ---

Glad you like it 🙂 > [@tachiko](#): > > Curious if my post inspired you a bit. > [This post](https://krita-artists.org/t/all-brushes-used-on-designated-layer-uses-set-blend-mode/57392/3) Actually, I was inspired by `Greater` blend mode that I learned from @SqueakyPancakes few days ago on Krita Users matrix server xD Your proposal could influence it tho maybe it floated somewhere in back of my head, who knows. How brain works is a mystery xD I have your proposal bookmarked, and I want to respond to it, but it requires a lot of pondering how to properly handle a use case like this, without breaking existing workflows. Basically a lot of words for - “I don’t know how to help you yet, because it’s a hard problem, but I’m thinking about it.” 😉 > [@tachiko](#): > > The video you showed looks great. > A little related.

Potentially `Wet Modes` can almost double the amount of current blend modes, so it might be needed to think how to improve the UX xD > [@tachiko](#): > > I used some Greater blend mode in this setup as well: Nice, I will check it when I will have more time (buried under commission work currently and I have a cold xD). Maybe it will spawn new ideas in my head 🙂 Thx for your input! 🙂 ---

@Sakura_Snow @CrazyCatBird @Nahum_Camacho Thank you, glad you like it! 🙂 I submitted a Merge Request, so if somebody wants to track or test the patch, the code is here: [Draft: New "Wet" blend modes (!1754) · Merge requests · Graphics / Krita · GitLab](https://invent.kde.org/graphics/krita/-/merge_requests/1754) I wanted to make a test build but… I don’t have enough disk space on my development SSD to make one xDDD so RIP lol @emmetpdx made a nice screenshot, so I’m pasting it. I will make more examples how to use new modes when I will have more time. ![image](https://krita-artists.org/uploads/default/original/3X/7/7/779828b895425d1225e260287b7c45f559631a95.jpeg) ---

Good effect! I even prefer to use it instead of “normal” when creating a new layer (unfortunately, there is no such option) ---

@Bea2 @kaichi1342 @EyeOdin @TheTwo I’m happy you like it! 🙂 > [@TheTwo](#): > > I even prefer to use it instead of “normal” when creating a new layer This blending mode is usually most useful as a `Brush Blending Mode` not as a `Layer Blending Mode`. When you use it as `Layer Blending Mode` it will often act the same way as not “Wet” modes. The only difference is when the background behind the lower layers is transparent or semi-transparent. Or, when layers are in a Group and `Pass Through` is OFF, then the “Wet” modes will act as on transparent, semi-transparent background. ![wet_normal_as_layerkra](https://krita-artists.org/uploads/default/original/3X/c/c/cca17bb6be0b3363e9b5c007f801df60c3fb2979.jpeg) It’s helpful for situations like this when you want layers to merge their Alpha softly, but it’s less common use case than `Brush Blend Mode` ---

@Konstrukto Not yet. I’m working on new math that will broduce 2 new version one that is a bit smoother and the other that produces delicate overlap that will be nice for some types of faster drying mediums. I move a bit slow recently because I’m covered by freelance work for now so not much time and fuel left on the end of the day. But I’m moving! 😄 I will post something new soon for feedback stay tuned! ---

Haven’t had much time this weekend, but at least I more or less settled with math that I will use for new Wet blending modes! I think… xD Here are the plotted functions I will use, if somebody likes this kind of stuff, you can check them out. (And moving sliders to see functions animate is kinda fun xD) > **[Wet Modes Blending](https://www.desmos.com/calculator/7ru40c0t7j)** > > Wet Modes Blending Coming days I will add them to Krita make test to be sure about exact parameter values I will want to use, and I will make some pictures for you guys 🙂 Hopefully even AppImage for test (if I will manage to borrow external SSD xD) ---
