Ok, we all know this panel where Violan's story is explained, right? (・・ ) ?
Well, this gave me an idea. ☆ ~('▽^人)
If Cale is the one who imagines this, it doesn't mean that he has a lot of imagination and that he should be able to paint at least with spots, right? ヽ(*⌒▽⌒*)ノ
That idea made me think about watercolors, and later about alcohol inks, which work in a similar way, look like this:
These are generated images of paintings created with alcohol ink and you can't tell me this isn't something you imagine Cale doing right? (⌒ω⌒)
Well these are my headcanon (@^-^):
Cale started painting because Record would record the landscapes he liked in his head and play them like a catchy song until he found a way to get them out.
This was the painting, it started when he accidentally spilled some wine on a piece of parchment creating a stain that reminded him of a landscape he saw, Record wasn't going to leave him alone anytime soon so he started stretching the stain forming the image and then he realized realized that Record was no longer playing that recording. That's how it all started.
Cale mixed the lower quality alcohol with different inks and began painting to get rid of the "catchy landscapes" and over time he began to enjoy the process of creating the ink and painting.
Violan discovered his hobby by accident after finding him painting at Henituse Castle.
She was amazed by his paintings and insisted on having an exhibition for them. Cale, unable to deny anything to his family, accepts, thinking that they were no big deal and planning to ignore it.
Unknowingly, he ended up becoming an art genius because alcohol ink had not been invented in Nameless 1.
