Accent or frame?
A short, distinct line acts more like a colour accent; a shape around the eye provides a stronger frame. Begin on a small area and check with your eyes open. A design seen on a closed lid reads differently in a natural gaze.
Vary the thickness too
Shade is not the only variable. The same blue or burgundy takes on a different voice in a fine or wider line. For a graphic effect, simplify surrounding colours; for softness, work with a gentle transition and a suitable product.
Use cosmetics intended for the eye area only where the manufacturer indicates. An arbitrary coloured product is not automatically an eye product.
Relate rather than match everything
A small clothing detail can echo the line, but every colour need not have a partner. An independent accent can be the idea. Treat official eye collections as a reference palette, not an obligatory shopping list.
