Learn how to use The Army Painter Flexible Triad Black & Greys to mix clean neutral shadows for miniatures. Step-by-step guide with common mistakes.
Quick answer
Use The Army Painter Flexible Triad Black & Greys to mix clean neutral shadows by layering from dark to light, avoiding muddy tones.
Why a dedicated black-grey triad matters
Neutral shadows require a controlled range of greys. Mixing black with other colors often produces muddy or desaturated results. The Flexible Triad Black & Greys provides six pre-matched shades from deep black to light grey, letting you build smooth transitions without guesswork.
Common pitfalls with grey scale shading
Using a single dark grey for all shadows flattens the model. Skipping the mid-tone step creates harsh jumps between light and dark. The triad's six shades encourage gradual layering, which preserves depth while keeping the shadow neutral.
How to mix neutral shadows with the Flexible Triad Black & Greys
- Basecoat with the darkest shade: Apply the deepest black from the triad to the areas that need the strongest shadow. This sets your anchor value. Common mistake: applying black too thickly. Thin the paint with a drop of water to keep detail visible.
- Layer the mid-dark grey: Use the second-darkest grey to cover most of the shadow area, leaving the deepest black only in recesses. This creates the first transition. Checkpoint: let each layer dry fully before adding the next to avoid blending into mud.
- Add the mid-tone grey: Apply the middle grey from the triad to the edges of the shadow zone, blending outward. This softens the transition. Common mistake: over-brushing the wet edge. Use a damp brush and feather the line gently.
- Highlight with the lightest greys: Use the two lightest greys to build up the lit areas adjacent to the shadow. Keep the lightest grey for the highest points. Checkpoint: if the highlight looks chalky, add a thin glaze of the mid-tone grey over it to unify the value.
- Glaze the whole shadow area: Mix a thin wash using the mid-dark grey and water (about 4:1 water to paint) and apply it over the entire shadow zone. This ties the layers together. Common mistake: using too much water. The glaze should be translucent, not runny, so it doesn't pool in recesses.
