Transparent White

1 of the 10 brands with a mapped match get genuinely close to Monument Pro Acryl Transparent White, though none is a clone. Brand by brand, the nearest colors are:

• Closest Citadel equivalent: Citadel Basilicanum Grey, close enough that batch variation matters more (delta E 1.6).
• Best The Army Painter option: The Army Painter Plate Mail Metal, a swap nobody spots at arm's length (delta E 1.5), but it is a metallic so treat it as a color reference, not a swap.
• From Tamiya: Tamiya Flat Aluminum 2, close enough that batch variation matters more (delta E 1.5), but it is a metallic so treat it as a color reference, not a swap.
• The Two Thin Coats pick: Two Thin Coats Carcharodon Grey, close, with a hint of drift side by side (delta E 2.4), but it is an opaque acrylic so treat it as a color reference, not a swap.
• Nearest in the AK Interactive catalog: AK Interactive Natural Steel, a near match with visible drift up close (delta E 3.0), but it is a metallic so treat it as a color reference, not a swap.
• Best Vallejo option: Vallejo Silver, close, with a hint of drift side by side (delta E 3.1), but it is a metallic so treat it as a color reference, not a swap.

Side by side the two agree in lightness and temperature; at delta E 1.6 the gap is smaller than the variation between two pots of the same paint.
