My name Carina Schröcker and I are opening a practice for clinical and health psychological treatment and advice. I need a logo for a business card, website, flyer, signage, ...
The logo should contain the Greek letter Psi - which stands for psychology. However, the letter should only be part of the logo and should be embedded in a harmonious, surrounding graphic. However, the logo should not be too complex.
My inspiration was a logo that I found on your site (see attachment). The lotus blossom can also be part of the logo, but I'm also open to alternatives.
The logo should be available in two color variants so that it fits on a black business card and white, light signage (practice) or for printing on white paper.
I also like a gradient like in the attachment. In terms of color, I like a rather dark berry farton.
I also like blue/green as in the attached example.
The logo should stand for psychology, harmony, holism and professionalism.
