When working with gradients on the canvas, you define a transition of colors along a line or a circle. Gradients are created using methods such as createLinearGradient for straight lines or createRadialGradient for circular transitions. Each gradient needs at least two color stops, which are set using the addColorStop method. A color stop specifies a color at a specific position in the gradient, where the position is a number between 0 (start) and 1 (end). The browser then smoothly interpolates the colors between these stops, creating a visually appealing effect. The placement and number of color stops influence how the gradient appears—more stops allow for more complex color changes.

You can combine gradients and patterns to create unique visuals. For example, use a gradient as the base fill and overlay a partially transparent pattern, or mask a pattern with a gradient to create fading effects. Try experimenting with different blend modes, alpha values, and layering techniques to achieve creative results that make your canvas drawings stand out.
