Filters

Filters are a variety of operations that allow users to manipulate and enhance the colors and materials of their pixel models. These filters enable creative control over the visual appearance of pixel grids, making it easy to achieve the desired aesthetic.

Note

Foxel utilizes an indexed color system, which means that colors are represented by a limited palette of predefined colors. When applying color filters, the resulting colors are calculated and then matched to the closest available color in the active palette. This ensures that the final appearance remains consistent with the selected color options, while also allowing for creative adjustments.

Important

If there are selected pixels in the active pixel grid, any filter will only apply to these selected pixels. Otherwise, all pixels from all selected Pixel Layers will be affected.

Available Filters

The available filters work similarly to those described in the Voxel Modeling section, but they are specifically designed for use with pixels and Pixel Layers instead of voxels and Voxel Layers.

The following links will direct you to the descriptions in the Voxel Modeling section:

Filter	Description
Adjust Hue/Saturation	Modify the hue, saturation, and lightness of the pixel colors.
Adjust Brightness/Contrast	Change the overall brightness and contrast of the pixel grid.
Color Overlay	Blend the pixel colors with a selected color for unique visual effects.
Desaturate	Reduce the intensity of colors, creating a more muted appearance.
Invert Colors	Reverse the colors in the pixel grid to their complementary counterparts.
Reduce Colors	Remap the colors in the pixel grid to a target color count.
Replace Color	Replace target colors in the pixel grid with a replacement color.
Replace Material	Replace target materials in the pixel grid with a replacement material.
