Underpainting Studio

Simplify shapes for your block-in, check values with a movable value finder, isolate colors or color groups from your image, and build palettes for color mixing.

Understand your reference. Plan your block-in. Paint with confidence.

Underpainting Studio helps artists break complex reference images into manageable shapes, value groups, and colors. Explore your image, compare simplified versions, and prepare a painting plan—from the first block-in to mixing with your selected paint pigments.

SIMPLIFY SHAPES AND PLAN YOUR BLOCK-IN Posterize your reference and adjust the level of simplification to reveal larger shapes. Compare shape levels and organize your image into block-in groups so you can focus on the big relationships before adding detail.

EXPLORE VALUES Switch between color, grayscale, and underpainting modes. Choose the number of value levels to group your reference into lights, midtones, and darks. Use the customizable, movable value finder to examine specific areas and understand how their values relate.

ISOLATE COLORS AND COLOR GROUPS Isolate a single color or a group of colors from your reference to see where they appear throughout the image. Identify warm, cool, earth, and neutral colors, and study individual regions more closely.

BUILD YOUR PALETTE AND EXPLORE MIXING Select Gamblin paint pigments to create your own palette. Use the color-mixing tools and mixing guide to explore mixtures based on the pigments in your selected palette.

COMPARE SIDE BY SIDE Compare versions of your reference side by side to see how different shape, value, and color groupings affect your painting plan.

STUDY YOUR COMPOSITION Use rule-of-thirds, golden-ratio, and diagonal guides to examine the placement and relationships of elements within your reference.

GET HELP AS YOU WORK Access quick tutorials or turn on Help Mode for guidance while using the tools.

SAVE AND TAKE YOUR STUDIES WITH YOU Save and transfer projects, save images, and print studies to keep your reference analysis close at hand while you paint.

Whether you are studying a subject or preparing your next painting, Underpainting Studio helps you see the essential shapes, values, and colors more clearly.
