Middle Blue is a mid-tone vivid blue with a cool undertone. For modelling, drop to French Blue in the recesses and step up to Aircraft Blue on the edges, both Humbrol paints. Substitutes are thin here, with Citadel Calth Blue Clear the closest same-finish option at 76 percent and no brand hitting the strong-match bar. Cross-brand swaps are adjust-on-model territory here, useful as a starting point rather than an exact replacement.

We ran Humbrol Middle Blue against every mapped catalog and came up empty: no brand makes a color close enough to call an equivalent.
Even the nearest color, Citadel Calth Blue Clear, dries slightly more muted and warmer than Middle Blue, so any substitute will change how the scheme reads.
