![]() Your entire project is now converted to grayscale. Algorithm differs from the one used in Gimp ( also named ‘Color to Alpha’ ) : Krita use CIE deltaE 0 function to calculate the difference between the image and the base color, so it is more flexible and configurable. Click OK when you have adjusted the settings. To find the feature, in the menu : Filter > Color > Color to alpha. To disable Alpha channel can be useful to. You can change the other settings if you have a specific color profile to which you need to convert the project, such as changing the Depth or Profile. To disable color channels can be useful for advanced editing techniques, like when using Separate Image feature. Then, select Grayscale/Alpha from the list of options. In the Convert All Layers window, open the drop-down menu next to Model. To change the color mode to grayscale, go to Image > Convert Image Color Space. You can change the color mode at the end of the process once you have created the project using a full-color mode such as RGB. If you want to change the color mode of the entire project to grayscale, you can change the document's color mode. How to Change the Color Mode of a Project to Grayscale However, the edit is destructive, and you can’t toggle the filter on and off as in the previous method. Your image is now converted to black and white without affecting the layers below or above. You can also use the shortcut Shift + Control + U on Windows or Shift + Command + U on Mac.įollow the previous section to determine the right Desaturate Method for your image, and click OK. Then, add a filter to the layer by going to Filter > Adjust > Desaturate. To only change the image layer, select it in the Layers docker. 1.Add the image as a new layer to the project by copying it from a separate tab and pasting it into your project tab. ![]() If you only want to change the image layer’s color to black and white, you can do this without affecting the layers below the image layer. Quick Clipping Group adds a new empty layer on top that works as the clipping layer, so you can immediately start painting on it.If you want to hide the filter layer to see the image in color again, you can toggle the filter layer visibility on and off by clicking on the Eye icon in the Layers docker.Ĭan You Convert an Image Layer to Black and White Independently? So when you're using the Quick Clipping Group option, you have to select your base layer(s) containing the drawing, not an empty layer - If you have multiple base layers use Ctrl+click to select them all first. A layer with alpha inheritance active takes the opacity from all the layers below it (while any kind of mask can only affect the layer it's attached to), that's why you have to separate your base layers from the background by putting them into a group, together with the alpha inherited layer(s) placed at the top of that group. Here, it's a layer property called Alpha Inheritance that you can activate by clicking on the little α icon on a layer in the Layers docker (the alpha channel stores transparency, hence the name). In Krita, clipping works differently than other applications like Photoshop. ![]() If you want to use clipping masks / layers, first you have to make sure that the drawing on your base layer is filled opaque everywhere you want it to be (like a paper cutout), because a clipping mask can only work on the pixels that aren't transparent. Or you could set the blending mode of the base layer with your grayscale drawing on it to Multiply or Linear Burn and make a new layer below it (not above) where you paint the colors. You could also use the blending mode Overlay (Is that what you tried?), which can not only change the color but also brighten and darken the layers below, depending how bright the color you're painting on the Overlay layer is (where 50% brightness is neutral). For example, you can make a layer above the others and set the layer blending mode to Color, which only changes the color component where you paint and takes the brightness from the layers below. ![]() There are different ways for coloring over grayscale. I'm not sure if I follow your description correctly. ![]()
