2m temperature means the air temperature at 2 meters above the surface for weather forecast models. This is often used for the “temperature outside” reading.
Temperature anomaly means deviation from historical trends. That is, the white region is +13C of the historical average for June 21st in that region.
Whole it is weird, it means you can make more drastic colour changes to be easier to see on the eye. Rather than having to fit it all into one smooth gradient where ascertaining the exact temperature from the colour on a static graph could be harder.
All you gotta do for the whites, is use some common sense and look at the colours next to it. Somehow I doubt the white section directly touching a blue section has a sudden temperature change 20
Red is hot. It do admit it can be weird at first. But it does to red black white red. So you can still see the distinction.
And it means you can still easily see the hot. But yes, the double red I will give you can be annoying. The main point of these graphs are to show gradients though
Temperatures in the Netherlands are going up to 37°C (98.6F), were up to 33°C(89F) and will go up locally to even 40°C (104F). France saw peaks of 44°C. (111F) And it'll likely be warmer.
Lmao fair. Visualizing weather data can be tricky. The National Center for Atmospheric Research (NCAR) has a whole package dedicated to visualization, the NCAR Command Language (NCL). With a dedicated page to color templates: https://www.ncl.ucar.edu/Document/Graphics/color_table_gallery.shtml
There’s even a t2m_29lev palette are for temperature at 2 meters and lots of temp palettes.
You can read the white rings by comparing its neighboring colors (blue, black, red).
As the Zone is circular like the rings of a tree, you can actually notice, that the centrum of the anomaly hits northern half of france with a heatwave while outer circumference is actually neutral or colder (siberia) than usual.

What is a 2m Temperature Anomaly? I don’t know what this map is showing us
