I've updated must have, selected colors, attached examples of stylized lives.
Here is what I wrote:
Hi,
I looked through designs, and I can say now what I want:
A leaf with BasicNutra or Basic Nutra inside that leaf.
Whether a leaf and words inside are just lines, or leaf has solid color background or ..
I leave to designers to decide.

Feedback please.

check bn3 example. leaf contours and BasicNutra can be just lines on white background
OR
the whole leaf green with BacikNutra white

I think solid green leaf with BasicNutra in white inside the leaf. This way BasicNutra will be well visible.
