ΔE 14.3, fair: the same colour family, but not a straight swap. Clear Magenta is a little darker, more muted than Power Node Glow. They are different kinds of paint: Army Painter Power Node Glow is an opaque base/layer paint and Reaper Clear Magenta is an ink, glaze or transparent paint, so they won’t behave the same on the model even where the colour is close.
Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 14). Clear Magenta is a little darker, more muted than Power Node Glow. They are different kinds of paint.
The same difference applies the other way round: Power Node Glow is a little lighter, more saturated.
ΔE is the colour difference between our two swatch estimates: under about 6 is close, over about 15 is loose. Real paints also differ in finish, coverage and how they thin, so test before you commit.
