ΔE 4.6, very close: most people won’t see a difference side by side. Titan Green Pale is cooler than Howling Sand. They are different kinds of paint: Army Painter Howling Sand is a one-coat contrast-style paint and Golden Titan Green Pale is an opaque base/layer paint, so they won’t behave the same on the model even where the colour is close.

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.
