Synesthesia in Vibrance

My background in Synesthesia.


Today my color-grapheme Synesthesia was heightened, much more vibrant than it's been in a while. I don't know why. It was accompanied by a dull headache all day.

I first noticed that the normal green & purple auras around some letters in text were green & red, a first. On top of that change, there were more red auras than there are purple on any normal day ("normal" as defined by my world). That faded by the end of the day back to my normal.

Additionally, groups of numbers were also getting a per-group aura. So at work when I saw a cost center number of "20157" the entire grouping of numbers had a red background/aura to it. It seems the 5 took dominance. Similarly the number "20138" appeared as green blending into yellow, due to the proximity of the 3 and the 8. Both of these had a little bit of blue on the left, due to the "2" to start. Sometimes I see a color aura, sometimes the numbers are actually in the color.
This all makes sense to me, and I documented the colors I usually see for single digits as follows:

1 - sometimes yellow, sometimes nothing distinct
2 - blue
3 - green
4 - orange
5 - red
6 - no distinct color
7 - no distinct color
8 - yellow
9 - usually reddish
0 - no aura, but in my head the digit 0 appears white
