People on TikTok are seeing numbers as colors and it ‘just makes sense’
People on TikTok are describing how they see numbers as colors and the revelation makes complete sense to some, but has others really confused.
It sounds a little far-fetched, but it’s actually a real condition called synesthesia that loads of social media users are suddenly discovering they have.

TikTok users are seeing numbers as colors
Videos are flooding TikTok that see people matching numbers to colors. For example, 2 could be pink, 7 could be yellow and 12 might be blue.
Essentially, people are saying when they picture the number in their head, they see it as being a certain color.
“The number 2 is like neon highlighter yellow,” one person said. “4 is baby pink and 6 is green, like light green. I am seeing that in my brain.”
It goes much further than colors too. In another viral video, a woman explains that certain maths equations relate to days of the week.
“7 x 7 = 49 and that is the same thing as Thursday,” she said as her friend listened in disbelief. “5 x 5 + 25 and that is Friday.”
She continued to say that November “gives off the same vibe” as Thursday, but the friend just didn’t understand it.
It’s a real condition called synesthesia
This isn’t just a random TikTok trend, it’s a real thing called synesthesia, which is when your brain routes sensory information through multiple unrelated senses.
As explained by Cleveland Clinic, this causes you to experience more than one sense simultaneously. For example, tasting words or linking colors to numbers.
This sensory crossover is not a medical condition and doesn’t have any negative attributes. In fact, many find it useful to help them remember information.
Your brain relies on your five main senses – sight, sound, smell, taste and touch – in everyday life and uses them to detect, signal and process things.
However, people with synesthesia experience the processing step differently, so their brains process the same information through more than one brain area at once.
Due to the huge number of sensory combinations in our bodies, there are at least 60 different forms of synesthesia.
‘It makes perfect sense to me’
TikTok users say the idea of numbers being colors and equations being months “just makes sense” and many are just discovering that they have the condition.
One person wrote: “I think I have synesthesia because it makes perfect sense to me.”
“4 x 4 = 8 is definitely brown,” said another.
A third person added: “Me realizing I have synesthesia.”
“5 x 5 = 25 is so red to me,” another argued,
Someone else said: “I think I also have synesthesia.”
