Colours Are Numbers

This is my college essay, please provide some feedback!

Songs have colours, colours have numbers, but songs don’t have numbers, and numbers don’t have colours. My brain had set rules for me, rules which are impossible for me to stop following. I can’t listen to music without seeing a colour, I can’t look at a colour without seeing a number.
I thought about this feeling that I had when I was younger, wondering why nobody else was talking about it, so in turn I also never talked about it. I saw a video not too long ago, informing about something called ‘synesthesia’, so I watch it out of curiosity. I become enthralled and so fascinated when the video is describing my exact brain process that I’ve always had but never commented about. Everything clicked in my mind as to what this process in my brain is called. Now, finding the name for the condition didn’t change these rules I have for myself but it changed how I view them. I instantly became more curious about it, rather than secretive. I have more of an understanding about how my brain has a different framework than typical people, surprisingly only 2% to 4% of people have synesthesia. My mind connects things together that people usually never have done. A song isn’t just music, it’s a colour, a combination. The same rule applies to a colour, it isn’t only a colour, but it’s a number.
My brain is oddly strict about it, too. A colour is forcibly connected to a number, but it’s impossible for me to look at a number and connect a colour. For example, I’ll see a coloured diagram or chart, and I only start to look at the numbers in my mind. It is also a massive challenge for me, especially in chemistry. It takes me longer to do a titration lab, because the colours continue to change, which I take note of. Conversely, I am exponentially better at chemistry over other subjects because I recognise changes in colours very easily. I know a colour changes when the same number isn’t seen in my brain anymore. I am still fascinated by the fact that I can look at a paper that has an array of numbers on it, and only think about and see a black and white paper. The numbers are black, the paper is white. I could be given a paper with different colours on it, and it would also be filled with numbers, except only for me.
I have forced myself to become an adaptive thinker due to this condition, though. I had to be innovative with my learning style and change how I learn, solely because I literally see the world differently. It becomes extremely difficult, but I have conditioned myself to manage it in certain situations. For example, when I am faced with a difficult formula or problem written on paper, I can’t physically map it out. I need to mentally map everything out in a way that I can connect to colours, because, again, I either think about both a colour and a number, or neither. Both need to be present in my mind. I map everything in my head in a way that makes sense for me, not to anybody I try and explain my difference to.
I have a goal to bring my unique outlook into laboratory medicine and a forensic field. Somebody who is analysing chemical spectrums or a panel for blood could think it is very chaotic, but I can separate everything in my head into numerous buckets, which are the colours and numbers. My mental organisation skills are something I wish I could teach people how to do, because it is so useful for me.
         My brain will always follow its own laws, songs with colours, colours with numbers, but when I am in a lab, I will turn data into a whole new form of perception.
