Color Matching From Reference Photos: When Hex Codes Help and Mislead

Choose a Reference Image That Contains Useful Color Information

A reference photograph can provide a starting point for a miniature painting scheme, but its usefulness depends on how the image was made. A photograph taken under colored lighting may shift an entire uniform toward blue or orange. Strong reflections can make metallic surfaces appear almost white, while deep shadows can turn an otherwise neutral fabric into an apparently saturated color.

Look for photographs with visible midtones, reasonably even illumination, and enough detail to distinguish adjacent materials. A full photograph of a vehicle, uniform, or animal may provide useful overall relationships, but close-up images are usually better for examining individual surfaces. Save the original image and avoid repeatedly sampling compressed copies.

Use Hex Codes to Organize the Color Palette

A hex code represents a digital RGB color using six hexadecimal characters. For example, #7A4938 describes a particular reddish brown in an RGB color system. This is useful when documenting a reference, comparing sampled areas, and communicating a consistent color direction between painters. It also makes a palette easier to store in a spreadsheet or digital planning document.

Sample more than one area of each important surface. A red uniform may contain a dark burgundy shadow, a muted middle red, and a lighter highlight. Recording only the brightest point creates an incomplete impression of the actual material. A three-point palette gives a more useful starting structure and makes it easier to plan base colors, shading, and highlights.

• Shadow sample for the darkest visible color.
• Midtone sample for the dominant surface appearance.
• Highlight sample for the brightest painted area.
• Optional accent sample for trim, markings, or contrasting details.

Why Digital Color Values Do Not Equal Paint Colors

A hex code describes a color displayed through a digital color system. Miniature paints are physical materials with their own pigments, binders, opacity, and surface finishes. Even when a paint appears close to a sampled digital value under one lamp, it may look different under daylight or warm indoor lighting. Screen brightness and color calibration introduce additional differences.

Paint also changes appearance according to the surface beneath it. A translucent glaze over a light base produces a different result from the same glaze over black primer. Matte varnish scatters light differently from gloss varnish, and metallic pigments introduce reflections that ordinary RGB samples cannot describe. A digital value is therefore a reference point, not a complete paint specification.

Translate Samples Into a Practical Painting Recipe

Start by identifying the role of each sampled color. A medium brown might become the main armor color, while a darker brown supplies recess shading and a pale tan provides edge highlights. Find paints that occupy similar visual positions in your available collection. Exact numerical matching is less important than preserving the relationship between the three colors.

For example, a reference photograph might suggest a warm olive uniform with dark green shadows and dusty yellow-green highlights. Begin with a suitable olive base, shade the recesses with a darker green-brown, and introduce a restrained yellow-green highlight. If the result looks too saturated, introduce a neutral earth tone. If it looks too cold, adjust the mixture toward yellow or brown. Record the actual paints and approximate mixing proportions.

Account for Miniature Scale and Viewing Distance

A miniature is usually viewed from a different distance and angle than the object in a reference photograph. Small surfaces need clear tonal separation to remain readable. A uniform that looks appropriately subtle on a full-size soldier may appear almost featureless on a 28 mm miniature. Slightly exaggerating highlights and separating shadow areas can preserve the intended appearance at gaming distance.

Consider the miniature's surrounding colors as well. A warm brown can appear cooler beside orange armor, while a pale gray may appear warmer against a dark blue base. Check the complete model under the lighting normally used for painting and photography. A successful match should work as part of the miniature's overall scheme, not only as an isolated patch of color.

Build a Reference Record You Can Reuse

A useful color reference record includes the original photograph, sampled hex codes, physical paint choices, approximate mixing ratios, and notes about the intended finish. Keep separate entries for base, shadow, and highlight colors. If a recipe changes after painting additional models, update the record instead of keeping several conflicting versions.

For club projects and coordinated armies, this documentation helps multiple painters maintain a recognizable shared palette. It also makes later additions easier when an older unit needs reinforcements. The next time a reference photograph catches your attention, save the image, extract three representative colors, and write down a physical paint combination for each before committing to a complete model.
