it looks like some random abstract artwork at first glance, but it's something cool i found about inks

(maybe someone found out about it before, i don't know)

a small accident led me to this - how inks react with bleach

(please don't be dumb, always be careful when working with bleach!!!)

description in spoilers!

water based inks are very reactive - when applied to dried inks -> both purple and blue are almost completely erased, black has "burnt" effect similar to the one seen on shirts. red is similar to black
when bleach was applied to wet inks/ink was dropped onto bleach -> inks, except for black, became "clunky", giving a cell-like effect and discoloration when spread. blue ink was especially interesting - it changed color to black, then, as it dried up, turned back to blue. red turned pink, then after spreading discolored, after drying pink spots turned red/orange

acrylic-based inks (koh-i-noor) and white markers aren't as reactive - some changes can be seen on black ink but nothing spectacular
gel inks don't seem to react
alcohol markers and classic pens have similar discoloration as black ink

brands differ, and i think it'd be best to test things yourself before working with bleach and inks. always be careful, work in properly ventilated environment, safety and all that
