This allows you to create interesting and stylized screentone-like effects. | 95 | Krita's brush engines also allow you to use :ref:`option_texture`.

| 102 | **Off-canvas** mixing has basically always been a core tool for artists everywhere; when we think of the stereotypical artist we might imagine someone with a few **brushes** in one hand and a wooden **palette** in the other. Whether it's oils, watercolor, or other traditional media, for the artist to have absolute control over their colors it's crucial to have some kind of palette, plate, jar, or other **off-canvas area** to mix colors together. While it's easy to overlook this in digital painting (where selecting fresh new colors without mixing at all is both easy and free*), Krita has a few very useful and unique features for off-canvas mixing. | 102 | **Off-canvas** mixing has basically always been a core tool for artists everywhere; when we think of the stereotypical artist we might imagine someone with a few **brushes** in one hand and a wooden **palette** in the other.

| 109 | Krita, like almost every art and graphics program, has a :ref:`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. | 109 | Krita, like almost every art and graphics program, has a :ref:`color_picker_tool` which allows you to very quickly sample a color from any pixel on your canvas.

| 111 | 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! | 111 | And still, there is more to this little tool than meets the eye!

| 117 | The Color Picker Blending feature changes the way that picking colors has traditionally 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. | 117 | The Color Picker Blending feature changes the way that picking colors has traditionally 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. | ||

| 119 | 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 combination 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: what percentage of sampled color is mixed together with your current brush color! | 119 | You can use Color Picker Blending much like a physical paint brush in traditional media.

| 121 | 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. | 121 | 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.

| 123 | 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 +` |mouseleft| shortcut. | 123 | 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.

| 127 | 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! | 127 | Clicking and dragging the Color Picker around the canvas currently causes it to sample many times as it switches pixels.

| 132 | Somewhat hidden away in the **Dockers** menu (:menuselection:`Settings --> Dockers --> Digital Colors Mixer`), this can be a useful tool for off-canvas mixing. The Digital Colors Mixer looks a little bit like an audio mixing board that you'd see in a recording studio, but instead of mixing music it mixes colors! It contains 6 independent **color mixers** that mix your current brush color with any color of your choosing. | 132 | Somewhat hidden away in the **Dockers** menu (:menuselection:`Settings --> Dockers --> Digital Colors Mixer`), this can be a useful tool for off-canvas mixing.
