Hue / Saturation is for quickly adjusting the overall color feel of the image. It is useful when you want to shift the mood a little or create color variations from the same artwork.

Eraser Tool is the basic tool for turning drawn pixels back into transparency. It works for both tiny one-pixel cleanup and larger erasing with a broader brush.

Selection Tool is used when you want to define an editable area or cut something out. It offers three methods: rectangle selection, freehand selection, and automatic selection based on similar colors.

Bucket Tool is used to process a closed area all at once. In addition to normal fill, it also supports erase fill and dithering fill.

Save / Load Palette lets you save the colors used in an image and later load a saved palette back into the current artwork. It is useful when you want multiple assets to share a unified color style, or when you need to work within a fixed palette for game development.

Dithering Pen Tool draws using the selected dithering pattern instead of laying down a solid color. It is useful when you want to place color as texture or pattern rather than as a flat fill.

Dither Pattern Editor lets you create and save your own dithering patterns. It is useful when the built-in patterns are not enough and you want a texture that matches your own art style.

Reduce Colors groups nearby colors together to simplify the palette. It is useful when you finish drawing and realize that the color count has grown too large or that the image would benefit from a cleaner, simpler color structure.

Color Balance does not shift the whole image in one flat step. Instead, it lets you adjust the color feel separately for Shadows, Midtones, and Highlights, which is useful when you want to refine the mood more carefully.

Pixel Refine loads an image and rebuilds it for pixel-art work based on a square that you define as “one pixel.” It is especially useful when you want to clean up AI-generated images or blurry scaled graphics so they are easier to use as game assets.
