Who is Macragge Blue Spray for?

It is for painters who want a blue undercoat and base color across several models. It is a poor fit if you only need a small brush-on touch-up paint.

When does this version make sense?

It makes the most sense when a large part of a model or army needs the same blue starting coat. Games Workshop describes the spray as a way to simplify undercoating and basing and specifies a smooth matt finish.

Can the ΔE matches replace the spray?

Only as color references. The match table compares recorded color coordinates; it cannot account for aerosol application, surface preparation, can coverage, or how a brush paint behaves over primer.

What should you check before ordering?

Confirm that the listing is the 400 ml spray can. A bottle paint with the Macragge Blue name serves a different job even when the intended color is close.

Which catalog colors are closest?

ΔE compares the listed digital color values only. Each row also compares the stored catalog attributes — purpose, chemistry, application, effect, finish and opacity. A conflicting attribute is flagged as a mismatch, a missing one as unverified, and neither is a physical substitute. How these matches are computed.
