Colored Pencils Plus: Posca Markers and Colored Pencils

Course Curriculum

Lesson Description

This module is a dynamic mixed-media lesson that teaches artists how to combine the bold, opaque qualities of Posca markers with the precision and layered richness of colored pencils. In this module, students complete a vibrant still life of avocados by first establishing an underpainting with Posca markers and then refining the piece with colored pencils. This approach allows for strong color foundations, smooth transitions, and detailed texture work.

Exploring Posca Markers as an Underpainting Tool

The lesson begins by introducing Posca markers and explaining why they make an excellent base for mixed-media work. Posca markers deliver solid, opaque color that dries quickly and resists wax-based layering underneath it, making them ideal for laying down broad color areas and defining value shapes early in the process. Students learn how to select marker colors to represent light, midtones, and shadow areas in the still life before moving into finer details.

Blocking in the Main Forms

Once students have identified their shapes, they begin applying Posca markers to block in the avocados and background elements. This stage focuses on capturing the major value relationships and establishing a strong, colorful foundation. Rather than worrying about fine details, artists are encouraged to think broadly, using the markers to define the general feel of the composition and the direction of light.

Transitioning to Colored Pencils

After the Posca underpainting is complete and dry, the lesson transitions to colored pencils. Students learn how to work on top of the marker base without lifting or smudging the underlying color. The instructor highlights best practices for color harmony, pressure control, and layering order so that the pencils integrate smoothly with the marker tones without dulling their intensity.

Building Texture and Detail

Colored pencils are then used to add depth, surface texture, and refined edges to the avocados. Students explore how layer upon layer of pencil pigment develops natural texture, highlights, and subtle value shifts. Special attention is given to the skin variations of each avocado, the way light wraps around form, and how small highlights and reflected light bring realism to still life work.

Refining and Unifying the Artwork

As the piece nears completion, students focus on unifying values and sharpening focal areas. The lesson includes guidance on enhancing contrast, deepening shadows, and reinforcing key edges. By the end of this module, students will have a finished, richly layered still life of avocados and a deeper understanding of how to combine bold markers with colored pencils for vibrant, detailed artwork.

Specific Lessons

Lesson 1 - Materials and Sketch

In this lesson, we explore the materials and surface that will be used and create the sketch of the avocados with a pencil.

Lesson 2 - Posca Base

In this lesson, we apply Posca markers, creating an underpainting for colored pencils. We also begin with colored pencil applications.

Lesson 3 - Layering Colored Pencils

In this lesson, we continue with colored pencil applications, adding depth and complexity to the drawing.

Lesson 4 - Completing the Drawing

In this lesson, we complete the drawing by adding details and more colored pencil applications.
