Color fill
Fills the connected closed area with the current foreground or background color.
The Fill page describes the exact tool available in the online Paint Classic editor on Intellect.
Use this page when you need to understand how the tool works before opening the editor, preparing a simple drawing, editing a screenshot, making pixel-art details, adding annotations, or combining several Paint tools in one workflow.
The Fill tool keeps the classic closed-area bucket behavior, but its options can now turn the same connected area into a flat color, a gradient, a shaded surface, a fur-like texture, a translucent amoeba-style fill, pencil hatching, a stylized thicker inner edge, glossy edge highlights or overlapping gradient scales. Every effect is calculated from the active drawing color, so changing the color box changes the whole effect palette.
Fills the connected closed area with the current foreground or background color.
Creates a diagonal transition from a lighter shade of the active color through the base shade to a darker shade.
Builds a soft light center and darker outer edge from the current color.
Adds alternating bright and dark shine bands tinted by the active color, useful for metal-like areas.
Fills the region with the active color and overlays soft bright spots and curved highlights.
Adds darker shaded zones near the edges while preserving the main color inside the region.
Generates many short light and dark strokes clipped to the fill area to imitate animal fur.
Uses a partly transparent active-color layer with soft internal blobs and glossy highlights.
Fills the closed area with diagonal hand-drawn hatch strokes made from light and dark shades of the active color.
Keeps the active-color fill and adds an irregular thicker inner edge along the closed-area border.
Fills the region with the active color and adds glossy white highlights only near the inner border of the closed area.
Fills the region with overlapping rounded scales; each scale has its own soft gradient, highlight and darker lower edge based on the active color.
Paint Classic keeps the familiar desktop-paint model: choose a tool, select its options, pick foreground and background colors, then draw directly on the canvas. Fill follows that model, so its result depends on the current color box, the selected option state, the mouse button used for drawing, and the current zoom level.
For accurate work, start with the magnifier when the image contains small details. Then use Fill with a deliberate option choice: thin strokes for outlines, filled styles for solid areas, transparent selection or text modes when the background must remain visible, and larger brush or eraser sizes when speed matters more than pixel-level precision.
The online Fill tool is suitable for quick browser-based image editing without installing a separate graphics application. It can be used for educational drawings, simple diagrams, icon drafts, screenshots, annotations, retro-style paint art, and fast corrections before sharing an image. Since the editor runs in the browser, the workflow is immediate: open Paint Classic Online, choose Fill, set the necessary option, apply it on the canvas, and save or share the result.
