What are some methods to avoid the blending of colors due to opacity?

Use overlapping strokes: If you want to avoid blending of colors due to opacity, try to use multiple overlapping strokes instead of a single stroke. This can help build up the color intensity without causing blending.

Separate layers: Using separate layers for each color instead of a single layer can help reduce the chances of color blending due to opacity.

Adjust layer opacity: If you are working with a single layer, try adjusting its opacity. Lowering the opacity of the layer for each brush stroke can help prevent blending of colors.

Use a dry brush: A dry brush technique involves deliberately using a brush that is not wet enough to mix the colors on your painting surface, consequently avoiding color blending due to opacity.

Paint in layers: If you want to prevent color blending, try painting in layers by letting the first layer dry before adding the next layer. This can help to ensure that colors do not blend together.

Use stronger colors: Choosing stronger, more saturated colors can help prevent blending due to opacity as the colors will be more visible even at lower opacity levels.
