My most complex conlang is probably the pencil language, which is basically the english of my conworld (its grammar is very kitchen sink-like but it still spread everywhere)

I have an idea: A language which symbols have different colours in them, and it has complex logographs, (oh and annoying sounds :D)

This is it so far:

What have I made...

Example text "human is good" not sure if this will match the future grammar at all in the future tho, or if it'll be left to right or right to left

As writing was invented to either be carved in stone and clay or written in ink with a quill, it wouldn't make much sense for it to dependent on colour. However, it could be that there is a tradition of calligraphy (writing as visual art) associated with the writing system.

Also, what words do conjunctions usually form from (and, but, or, etc.)

Very often a preposition. The English word "and" comes ultimately from a Proto-Indo-European word that means "near/opposite/before".

I’m making a language with a really confusing pronunciation. Very few words have many vowels and there are unique sounds.

Hello is Kvnmyw /Kvnmɪʊ/

Actually, changing it to weird writing system with abstract logographs.

Oh no
