We will like a “unified” logo for our company and all the brands underneath it.
We have several independent websites, and now that we are creating a company that will unified all this websites, we need new logos for all of them, but they needed to maintain their “spirit”
The company name is "Ambiente et Odora S.L."
This name comes from Latin meaning "environment and odors", and under this company, there will be 5 different brands:
Olores.org (the most well known website, more than 10 years of life) https://www.olores.org/
SVPA (Environmental consultancy services) https://www.svpa.es/index.php/en/
Odora (new brand for Odour Environmental Consultancy)
PrOlor (The first commercial odour forecasting software) http://www.prolor.net/
Deodormatic (indoor odour abatement system) https://deodormatic.com/
The idea is that the logos should be related (for example: having the same typography, something in common, ...)

Texto del logo
We will need "6 logos", but they should be similar, so we need one main logo for Ambiente et Odora, and 5 similar but different logos for the brands. The idea is that the logos should be related (for example: having the same typography, something in common, ...)
Requisitos
Debes tener
- Same typography, for example, and the letters could be in dark grey instead of black. Olores.org should maintain the orange color....
Each logo should not have more than 3 colours
Agradable de tener
- A logo than can be used later for new possible brands.
Odors are usually represented as circles, or curvy lines, and almost all names have an "o" on it, so they could be replaced by a symbol, for example.
No debería tener
- No trees
