"F" and "S" in Lanvin Blue (see why in blue on point 5)
The other letters in metallic grey or orange (ocher like a Roland Garros tennis court).
We will try both to see what if we want more sophistication or creativity
As the full brand is "ForSea Investments", we could try to use the grey for the other letters of Foresea and the orange for "Investments"
Our Ideas and Additional Information:
I would like to use a kind of classical handwriting font and to transform the "F" and the "S" in two waves.
The 2 bars of the "F" could become a double wave (a small underneath and a bigger one at the top) while the "S" would be a big one.
As a very distant influence, you can have a look at this painting: https://en.wikipedia.org/wiki/The_Great_Wave_off_Kanagawa
Of course, the logo will need to be easily readable (sometimes handwriting fonts are not very readable).
I pick only 2 style inspiration because they where the only one I found were the logo is included in the letters.
