I never noticed it until recently , after lots of mental ups and downs that everytime made art during days where i felt soo enraged at myself or was upset to the point i couldn’t do anything else or just felt pretty useless – i used the color red . every single one . i noticed this cause i like putting dates on top of the pages . i once saw this video of a girl who was also a painter and her mum told her this same thing . thought it might be more common than i think ?
