+<ul>
+  <li>
+    Align the vertical edges in your graphics to the 4×1 grid to minimise
+    the effect of colour bleed.
+  </li>
+  <li>
+    Use the out of gamut colours of the Y ramps to your advantage, their hue
+    changes more than usual so they give some extra flexibility.
+  </li>
+  <li>
+    In situations where you can’t use the colour you want, try to match its
+    brightness so that the colour difference is harder to spot.
+  </li>
+  <li>
+    The eye is sensitive to edges, so de-block visible edges of colour bleeding
+    by adding detail or dithering in them.
