| The initial version of this test was relying on color | |
| composition and was predicting a lime-green-ish (#7FBF80: | |
| slightly desaturated lime green) background color for "thing". | |
| "#7fbf80 color description : Slightly desaturated lime green" | |
| https://www.colorhexa.com/7fbf80 | |
| This test does not rely on color composition but the | |
| test nevertheless verifies the ::selection overlay drawn | |
| over the ::grammar-error overlay. | |

| <p>Test passes | |
| <ul> | |
| <li>if each glyph of the sentence is yellow | |
| <li>if "thing" has a desaturated lime green background | |
| <li>if the other words have a very lite blue background and | |
