Yes, Kantor Blue is currently part of the Citadel (Games Workshop) range. Check local stock or equivalent alternatives if the pot is hard to source.
Check Delta-E, finish type, coverage, opacity, and behaviour over your chosen primer. Run a full test with one shade and one highlight pass before applying the substitute to an entire unit.

As a base paint, Kantor Blue requires specific handling that affects how any substitute performs. The colour sits in the deep blue range, with strong coverage and opaque opacity over a black primer.
Kantor Blue is designed to cover primer evenly in one or two passes. Coverage is rated strong, so a substitute that falls below this threshold will require extra coats to block the undercolour. Test the replacement over the same primer — a base that shifts tone with each coat can alter the entire highlight stack.
This base paint performs best over a black primer. A substitute that behaves well over a light primer may struggle over black or grey, especially if its opacity is lower. Apply two thin coats, letting each dry fully before the next.
The deep blue mid-tone of Kantor Blue anchors the layers above it. A replacement that dries glossier or rougher will change how shade and layer paints adhere.
Base paints carry more pigment than other types, so even a deep blue substitute with a close Delta-E can read warmer or cooler once shaded. Run a complete test: prime, base, shade, and highlight before committing.
The most useful partners for Kantor Blue are Macragge Blue (base colour), Drakenhof Nightshade (blue wash), Calgar Blue (layer / highlight) and Nuln Oil (primary wash). These supporting colours define how the base reads once the recipe is complete.
Macragge Blue, Drakenhof Nightshade, Calgar Blue and Nuln Oil are common companions to this base. They were chosen in the original recipe because their coverage, drying speed, and finish layer in the same workflow without forcing extra corrections.
A base paint substitute only becomes trustworthy once it survives the same primer, shade, and highlight sequence as the original recipe.
Looking at the surrounding palette matters because a near match can still push the finished model warmer, colder, or flatter than expected.
That combination of colour distance, finish, and recipe context is what makes a base paint substitute reliable on an actual miniature.

Looking at the surrounding palette matters too, because a near match can still push the finished model warmer, colder, flatter, or glossier than expected.
That is why the page keeps the recommendation anchored to painting workflow instead of treating Delta-E alone as the final decision.
A useful equivalent page should also reduce buying mistakes: the closer colour is not always the safer option if the bottle dries glossier, covers faster, or behaves differently on large armour panels.
