Old logo is in attachment, please note, we DON'T WANT skyscraper buildings, chimneys in it. Maybe houses but only if it looks really cool.
Also note regarding colors e.g. stripes, red and blue were made based on the national colors, this logo CAN NOT be based on those colors in same concept (i.e. If you wanna use red, use it smart and perhaps with other colors without blue and the same applies for blue) and should be neutral in that context.
Letters should be readable and recognizable.
Ambijent - RST - that dash between Ambijent and RST can be present in logo ONLY if it looks really cool, but most of time we would prefer RST below Ambijent, perhaps in bottom right corner or just below, so no dash there. Also it doesn't really matter if you use capitals, upper case or lower case letters as long as it looks good.
You can use letter A as the main source for the symbol or shape.
Furthermore, you can use existing elements from old logo e.g. stripes or circles, but logo has to be nothing like the old one.
Style we are after is modern, minimalistic and perhaps origami.
We would like to see every logo concept made in variations, one on black and one on white background.
Thanks for reading and good luck!
