Main design is focus on silhouette of company initial C and S.

I pick green color for the silhouette of letter C and S to represent money or finance.
... and there is one circle in gold color to represent gold coin.

As an alternative, I have the logo here in black / white / grey color to show how the logo looks like for basic black / white colors.

I scale down the logo small size to ensure the logo still visible on tiny size, for example to use for office stationary (name card, letterhead) or web page usage (as an icon for example).
