Tall Lancet Window With Layered Border Panels Coloring Page

A narrow lancet under a steep pointed arch, built from a grid of square panes with small diamonds set into their corners and a spine of interlocking cells running up the middle. The outer border stacks two layers of panes around the whole shape. The grid keeps this page methodical rather than difficult. Color the central spine in one strong hue and hold the flanking grid to two quiet values, and the vertical line pulls the eye straight up the window.
