our company's logo is the visual figurehead of your brand, so it's important to get it right. Whether intentional or not, every detail of your logo will influence people who see it. That's why nothing should be arbitrary.
In fact, it's in your best interest to make sure that every logo design choice is intentional and communicates the message you want to convey, because thoughtless design choices lead to misleading or logo design firms.
Worse, thoughtless choices can lead to logos that don't say anything at all.
