I like that it has the potential to stand out. However, I would like to see the Material Service testing on the same line and laboratories under it. Also, lets try some other color variations within the stated color preferences. thanks.
#12 is my favorite so far. Its clean, elegant and simple. Can we see some variations to that concept? Maybe fonts, sizes, more color (beige), some architectural, engineering or construction symbols.. something to make it pop.
#38 I like this a lot. The concept of an abstract logo. Helps with branding as well. Lets explore this concept a bit more. Also, its Material Service Testing Laboratories (not technology).
#37 I liked the MST from the beginning. Lets see if we can incorporate that MST into an abstract logo like here. PLease replace technology with testing.
#35 I like the stand alone logo, but the "gear" is not really applicable to what we test. We do concrete, steel, rocks, soils, masonry.. etc... can we incorporate some of these?
