Seasons im my region (SIMR) at the beginning of February 2018: I changed the 2017 colors (scroll all to the right) so that the intensity of the color is similar to the percentage of the season. That means the color is intense only when the season has arrived to 100%. This seems more logical but had the effect that the intense red for autumn 2017 occurred on Christmas only as the last indicator (fog) didn't arise earlier. At that time we had already more than 80% winter - this is somehow strange and isn't in accord with our everyday experience. I think I must think it over and find another color scheme. - This graphics shows the linear sequence of the seasons in my region, defined by the following self-chosen indicators:
