Summary of Issue: G18: Description
Comment (Including rationale for any proposed change):
Couldn't understand and translate the following description:

"If the background or the letters vary in relative luminance (or are patterned) then the background around the letters can be chosen or shaded so that the letters maintain a 4.5:1 contrast ratio with the background behind them even if they do not have that contrast ratio with the entire background. 



The contrast ratio can sometimes be maintained by changing the relative luminance of the letters as the relative luminance of the background changes across the page."



Proposed Change:
Need clarification. Please explain them by using more plain words.
