Colors are sixteen original ColorBrewer colors chosen by warming stripes inventor, climate scientist Dr. Ed Hawkins
The temperature range covered by each color was chosen as 0.12 °C per color, in order to use use all sixteen colors without clipping.
The "border" temperature between red and blue stripes was chosen as the average of the highest and lowest temperature values (not as an average of a date range as is customary in warming stripes).
