The image part of the logo (meaning that which does not include the name 'Preview Homes') should be able to stand alone and be independently recognizable.....and should be able to denote the use of video. I would imagine that there could be some type of house outline/silhouette.
I also want the logo to highlight or bring attention to the fact that this is not a '.com' domain, but rather a '.tv' domain.
Initial thoughts have been to have a '.tv' inside a home outline at the tale end of the URL......***However, please don't let this statement limit your creativity***
A maximum of two (maybe three) colors should be used. Possible colors are: RED, GOLD, ORANGE, GREEN ...and of course BLACK. This is my current order of preference. Think of bright & bold colors that would stand out on a FOR SALE sign and/or sign rider. I have attached the RE/MAX for sale sign for you to see their use of color.
ALSO....I tend to lean towards horizontal designs. Compared to logo at top with domain below.
