As you may have already read in the introduction, Krita's main goal is to help artists create digital painting from scratch. Krita is used by comic artists, matte painters and texture artists, illustrators around the world. This section explains some common workflow that artists use in Krita.
When you open a new document in Krita for the first time, you can start painting the instantly, The brush tool is selected by default and you just have to paint on the canvas. However let us look what artists do in Krita.
Below are some of the common workflows used in Krita:
Some artists work only on digital medium, sketching and visualizing concepts in Krita from scratch. As the name suggests a technique of painting done within matter of hours to quickly visualize the basic scene , character, look and feel of the environment or to denote the general mood and overall concept is called a speed painting. Finishing and finer details are not the main goal of this type of painting, but the representation of form value and layout is main goal.
Some artists set time limit to complete the painting while some paint casually. Speed painting then can be taken forward by adding finer details and polish to create a final piece.
Generally artists first block in the composition by adding patches and blobs of flat colors, defining the silhouette etc . Krita has some efficient brushes for this situation, for example the brush under Block Tag like Block fuzzy, Block basic, layout_block etc.
After the composition and a basic layout has been laid out the artists add as much details as possible in the given limited time, this requires a decent knowledge of forms, value perspective and proportions of the objects. Below is an example of speed paint done by David Revoy done in an hours time.

Often an artist for example a comic book colorist will need to take a pencil sketch or other line art of some sort and use Krita to paint underneath it. This can be either an image created digitally or something that was done outside the computer and has been scanned.
If your images has a white or other single-tone background, you can use either of the the following methods to prepare the art for coloring.:
Place the line-art at the top of the layer stack and set its layer blending mode to Multiply
If you want to clean the lineart a bit you can press Ctrl + L or go to
You can clean the unwanted greys by moving the white triangle in the input levels section to left and darken the black by moving the black triangle to right.
If you draw in blue pencils and then ink your line art you may need to remove the blue lines first to do that go to
now select Red from the drop-down, Click on the top right node on the graph and slide it all the way down. Or you can click on the top right node and enter 0 in the output field. Repeat this step for Green too.
Now the whole drawing will have a blue overlay, zoom in and check if the blue pencil lines are still visible slightly, If you you still see them, then go to Blue Channel in the color adjustment and shift the top right node towards left a bit, Or enter a value around 190 ( one that removes the remaining rough lines) in the input box.
Now apply the color adjustment filter, yes we still have lots of blue on the artwork be patient and move on to the next step. Go to Ctrl + Shift + U Now select max from the list.or press
|it is good to use non-photo-blue pencils to create the blue lines as those are easy to remove. If you are drawing digitally in blue lines use #A4DDED color as this is closer to non-photo-blue color.|
You can learn more about doing a sketch from blue sketch to digital painting here in a tutorial by David Revoy.
After you have a clean black and white line-art you may need to erase the white color and keep only black line-art, to achieve that go to. Use the dialog box to turn all the white areas of the image transparent. The Color Picker is set to White by default. If you have imported scanned art and need to select another color for the paper color then you would do it here.
This will convert the white color in your line-art to alpha i.e. it will make the white transparent leaving only the lineart. Your line-art can be in grey-scale color space, this is a unique feature in Krita which allows you to keep a layer in a color-space independent from the image.
There are many ways to color a line art in Krita, but generally these three are the common among the artists
Here, you start by making a mess through random shapes and texture, then taking inspirations from the resulting chaos you can form various concepts. It is kind of like making things from clouds or finding recognizable shapes of things in abstract and random textures. Many concept artist work with this technique.
You can use brushes like the shape brush, or the spray brush to paint a lot of different shapes, and from the resulting noise, you let you brain pick out shapes and compositions.
You then refine these shapes to look more like shapes you think they look, and paint them over with a normal paintbrush.
This method is best done in a painting environment.
This method finds it's origins in old oil-painting practice: You first make an under-painting and then paint over it with colour, having the dark underground shine through.
With Krita you can use blending modes for this purpose. Choosing the Color blending mode on a layer on top allows you to change the colours of the image without changing the relative luminosity. This is useful, because humans are much more sensitive to tonal differences than difference in saturation and hue. This'll allow you to work in greyscale before going into colour for the polishing phase.
You can find more about this technique here.
Many artists use Krita to create textures for 3d assets used for games animation etc. Krita has many texture template for you to choose and get started with creating textures. These template have common sizes, bit depth and color profiles that are used for texturing workflow.
Krita also has a real-time seamless tile mode to help texture artist prepare tiles and texture easily and check if it is seamless on the fly. The tiled mode is called wrap around mode , to activate this mode you have press W. No when you paint the canvas is tiled in real-time allowing you to create seamless pattern and texture, it is also easy to prepare interlocking patterns and motifs in this mode.
Starting from 2.9.7 Krita now has a new brush engine to support painting normal maps you can read more about it here
Krita can also be used to create high definition pixel painting. The pixel art look can be achieved by using Index color filter layer and overlaying dithering patterns. The general layer stack arrangement is as shown below
The index color filter maps specific user selected colors to the grey scale value of the artwork. You can see the example below, the strip below the black and white gradient has index color applied to it so that the black and white gradient gets the color selected to different values.
You can choose the required colors and ramps in the index color filter dialog as shown below
Dithering can be used to enhance the look of the art and to ease the banding occurred by the index color filter. Krita has a variety of dithering patterns by default, these can be found in pattern docker. You can use these patterns as fill layer , then set the blend mode to overlay and adjust the opacity according to your liking. generally an opacity range of 10% - 25% is ideal.
Paint the artwork in grey-scale and add a index color filter layer at the top then add the dithering pattern fill layer below the index color filter but above the artwork layer, as shown in the layer stack arrangement above. You can paint or adjust the artwork at any stage as we have added the index color filter as a filter layer.
You can add different groups for different colors and add different dithering patterns for each group.
Below is an example painted with this layer arrangement
