Description

  • The bit depth page could use some better examples.
  • The workflow page needs reading over.
  • The OCIO part of the workflow page needs to be fleshed out once ocio is fixed.
  • The color models page could use a lot of work.
  • The profiling and callibration pages needs to be remade from the ground up.
  • The catagory page itself needs a proper introduction to colors in the computer, and how to visualise color spaces.

Will do the profiling and callibration page having merged softproofing.

OCIO will need the cave image or something.

Models pages will... well, will need a lot of work :/

I'd like to add this section about "color picker blending" under the "off-canvas" section of the Mixing Colors page, and just above the section on the digital colors mixer docker.

Also, I rendered out a short example animation webm with Kdenlive, which I then converted to a gif using ffmpeg, but I've found it hard to match the quality of the other gifs on the page! Do you have any tips for improving my gif's image quality? (Kdenlive's gif renderer seems to be broken at the moment)

=== Color Picker Blending ===

{{NewInVersion|4.1}} Krita, like almost every art and graphics program, has a Color Picker tool which allows you to very quickly sample a color from any pixel on your canvas. While this tool may seem relatively simple and humble, it is also one of the most important and commonly used tools in the digital artist's toolbox - perhaps only second to the brush! In fact, the color picker tool is at the very heart of mixing colors, and is often used in combination with on-canvas techniques like glazing and scumbling to produce smooth blends of color.

And still, there is more to this little tool than meets the eye! Not only can you configure Krita's color picker to sample from the average color of a '''radius''' of pixels, Krita's Color Picker also has a unique '''blending''' feature: a powerful and intuitive tool for off-canvas color mixing!

The Color Picker Blending feature changes the way that picking colors has worked for decades; instead of completely replacing your current brush color with the newly sampled color, ''blending allows you to quickly "soak up" some portion of the sampled color'', which is then mixed with your current brush color.

You can use Color Picker Blending much like a physical paint brush in traditional media. If you were to dip your paint brush into a pool of ''blue'' paint, and then immediately dip again into a pool of ''red'' paint and paint a stoke across your canvas, the stoke wouldn't be pure red - it would be some mix of blue and red which would mix to create an intermediate purple color. Which shade of purple would depend on the ratio of paints that mix together within the hairs of your brush, and this is essentially what the Color Picker's "blend" option controls: how much percentage of sampled color is mixed together with your current brush color!

Not only does Krita's Color Picker Blending feel even more like mixing paints, it is also completely off-canvas and independent of opacity, flow, shape, and other brush settings. Furthermore, unlike most on-canvas mixing techniques, Color Picker Blending works regardless of the location of colors on your canvas - enabling your to mix with colors at any position, on any layer, or even in different documents! Quickly mix lighting colors with local colors, mix the ambient sky color into shadows, create atmospheric depth, mix from a preselected palette of colors in another layer/document, etc.

To use Color Picker Blending, simply set the "blend" option in the '''Tool Options Docker''' while the Color Picker Tool is active; setting blend to 100% will cause your Color Picker to work in the traditional way (completely replacing your brush color with the picked color), setting to around 50% will give you a half-way mix between colors, and setting to a lower value will create more subtle shifts in colors each click. Of course, blending affects both your dedicated Color Picker Tool as well as the <kbd>ctrl</kbd>+{{MouseButton|left}} shortcut.

'''Note:''' Clicking and dragging the Color Picker around the canvas currently causes it to sample many times as it switches pixels. You can use this trait to quickly soak up more color by "dipping" your color picker into a color and swirling it around. This can be pretty satisfying! However, this also means that some care must be taken to prevent from accidentally picking up more color than you want. It's pretty easy to click a single pixel only one time using a '''mouse''', but when painting with a '''drawing tablet and pen''' it can sometimes be desirable to use a slightly lower blend setting!
