Pigment Calibration
If a pigment tints differently than expected in your plaster, adjust its hex here. Changes save to browser memory.
Important Notes
This tool gives a starting-point estimate, not a guaranteed match. Every real-world formula needs a test sample on the actual substrate before you commit to a full batch. A few things the math cannot predict:
• Plaster dries 10–30% darker and shifts tone vs. wet — the preview shows predicted dry color, but your pigment load may need adjustment.
• Tinting strength of each Marblers pigment in your specific plaster medium (Venetian, Microcement, Roman Clay, etc.) varies — heavy-chroma colors may need less pigment than the formula suggests; neutral/earth tones often need more.
• Metamerism: a formula that looks right under shop lighting may shift under the client's actual lighting. Always check in the room.
• The Marblers pigment hex values are calibrated estimates. Use the Pigment Calibration panel above to refine them after you've test-mixed each pigment with your base.
Workflow tip: mix the formula at ½ the suggested grams first, trowel a small test, let it cure fully, then add pigment to match if needed. Write down every adjustment.
