Colors are distance to the pareto frontier for the given setting for "dealscope"! Easily noticed when axis and color are set to the same dimension (EG CPU) - but setting to different things allows you to visualize two dimensions (three, with price) without needing a 3D chart. I found it really useful to find outliers, but I realize it's a bit nonstandard!
Oh - and colors are grey-blue to red, with red being pareto optimal
It's great that you understand the chart. Yellow being more optimal than green is very far from intuitive to the rest of us. We read green then yellow then red as a sign of DECREASING fit. And a bunch of blues next to that green to red progression reads as "no data" or "not relevant" or something.
It's great that you have the data. I'm sure that took a lot of time to obtain. Spending a few more percent of your total time making the presentation of the data intuitive to others is almost certainly the highest ROI thing you can do at this point, if you want your site to be useful enough to get enough visitors to pay for the cost of acquiring the data.
Feel free to tell me that red is the lowest Pareto value and that's why you made the frontier red, or whatever. I'll still respond that the details of the presentation matters enormously to adoption, and the current presentation is very far from optimally intuitive to those of us who didn't personally develop the data.
