yellow
"Yellow is like red; a powerful dominant colour, most obviously representing warmth, sunlight or liveliness, but can also be a very harsh colour if used at its most intense."
"In general, I go through my day ignoring the sounds and colors that are triggered by life. Some colors though, like yellow and pink, are so loud that even a little will make my ears hurt. Yellow is like someone blowing a whistle, and pink is like someone scratching on glass. Autumn is the time when I get my worst migraines. I play trombone, and it's a distinct navy blue mist. Tubas are purple, and flutes are yellow. I actually switched from flute to trombone as a child when the bright yellow gave me headaches. Not just music, but noise has colors. My vacuum is distinctly orange, sirens are red and red sounds like a siren, and windchimes are like little silver confetti in the breeze. Recently I saw the online video for motion-sound synesthesia, and I had to ask my husband if the video really was silent. It's not something I consciously noticed before, since sometimes what I hear-hear and what I see-hear mixes up, so now I'm paying more attention to the "motion-sound" portion that is the soundtrack of my life."
"I won't lie, looking at pictures made me miss my friends. And warm summer days. And it made me crave for a big bouquet of happy yellow flowers like the one I made that day out of the flowers I found in my mother's garden. That yellow, it is quite magical, don't you think? It's like a big bowl of concentrated happiness. Yellow is like the best friend that shows up at your doorstep with a big smile - and it will make your day every time, no matter what."
"Yellow is like lemon sorbet for the home," he said. "It's like a crisp refreshing palate cleanser."
