Quick answer

Choose the Developer set if you need the widest ISO language coverage across DE, Spanish, Nordic, French, Swiss, and UK layouts. Pick White Mint for the same broad coverage with a brighter two-tone look, or Modern Blue if you type on a Nordic ISO board and want a lower-cost full set.

Layout coverage is the first filter

All three sets are ISO Cherry profile PBT dye-sub keycaps, so the real differentiator is which language layouts they cover. Developer and White Mint both include keycaps for DE, Spanish, Nordic, French, Swiss, and UK ISO boards. Modern Blue is built for Nordic ISO only, so it will not fill a German, French, or UK layout correctly.

If you might resell or move the set to another board later, the broader coverage of Developer or White Mint gives you more flexibility. If you are certain your board is Nordic ISO, Modern Blue is the simplest match.

Compatibility exclusions matter more than the color

The three sets share a similar Keychron compatibility list, but the exclusions are not identical. Developer and White Mint list the Q HE series, Q series (excluding Q8, Q9 Plus, Q10, Q11, Q60), Q Pro, Q Max series (excluding Q8 Pro, Q8 Max, Q10 Pro, Q10 Max, Q11 Pro, Q13 Pro, Q13 Max, Q14 Pro, Q14 Max, Q15 Max, Q60 Max), V, V Max series, and 81 Pro. Modern Blue lists Q series (excluding Q8, Q9 Plus, Q10, Q11, Q60), Q Pro, Q Max series (excluding Q8 Pro, Q8 Max, Q15 Max, Q10 Pro, Q10 Max, Q11 Pro, Q13 Pro, Q13 Max, Q14 Pro, Q14 Max, Q60 Max), V, V Max series (excluding V8, V8 Max, V10, V10 Max), and 81 Pro.

Before ordering, check your exact model against the list. A set that fits one Q Max board may not fit another, and the V series exclusions on Modern Blue are a common trip-up.

Color and price trade-offs

White Mint and Modern Blue both carry a catalog comparison price of USD 39.99, but their current catalog prices differ: White Mint is USD 28.39 and Modern Blue is USD 25.59. Developer is also USD 25.59. The small gap buys you either broader layout coverage or a different colorway, not a different material or profile.

All three are dye-sub PBT, so legends are designed to resist wear and the Cherry profile keeps a familiar sculpted feel. None of the sets includes a keyboard, so budget for the board separately.

Key trade-offs to weigh

  • Coverage vs. simplicity: Developer and White Mint cover six ISO language layouts; Modern Blue covers Nordic only. Choose broad coverage if you are unsure of your layout or may change boards. List your required language layout before comparing colors.
  • Compatibility list vs. assumption: Developer and White Mint list Q HE series support, while Modern Blue does not. Modern Blue also excludes V8, V8 Max, V10, and V10 Max, which the other two do not list as excluded. Match your exact keyboard model to the exclusion list, not just the series name.
  • Price vs. color preference: White Mint costs USD 28.39, while Developer and Modern Blue cost USD 25.59 each. All are PBT dye-sub Cherry profile sets, so the premium is for the White Mint colorway and broad coverage combo. Decide whether the White Mint look is worth the small price difference for your build.

Product facts at a glance

Which set fits your build?

Best for

  • Typists who need DE, Spanish, Nordic, French, Swiss, or UK ISO coverage in one set (Developer or White Mint).
  • Nordic ISO users who want a lower-cost full set and have confirmed their board is not an excluded model (Modern Blue).
  • Buyers who prefer a brighter two-tone colorway and do not mind paying slightly more (White Mint).

Not for

  • Anyone with a keyboard model that appears in the set's exclusion list, such as Q8, Q9 Plus, Q10, Q11, or Q60.
  • Nordic-only typists who need the lowest price and do not require broad language coverage (choose Modern Blue over Developer or White Mint).
  • Buyers who expect a keyboard to be included; none of these sets includes a keyboard.
