If you look at the “total queries over the last 24 hours” graph, the blocked queries here are grey, but the “queries blocked” box is light blue. The “queries answered by” chart also uses blue for the blocklist portion, even though the “percent blocked” box uses yellowish. And then the “domains on blocklist” box uses red, as does the query log, while the “top blocked domains” list has grey frequencies. These colors are as of v5.1.
I propose to combine the "queries blocked" and "percent blocked" boxes into one long box, like 20,000 (20%). Then color everything referring to blocked queries as a whole one color, say grey, and everything referring to a specific domain (plus the "domains on blocklist" box) red.
