Hi yayuk! Thank you so much for your participation in our contest. We like the fact that you tried a full spectrum color options in one of your concepts, it's a good direction and we'd like to see more options from you. We like the pictorial mark but would like to see something more detailed, masculine and powerful looking, something that really stands out from a white or dark background. Thank you for providing an option with a dark background so that we can see the difference. I actually really like that color spectrum in the word "Spectrum" but worry that the all the colors in the text and in the mark might be too much all together. Could we see some options with some differing font (something a bit more unique and bold than there is now) and differing color options? We probably don't want grey used in the text as it wouldn't stand out on a grey uniform. We prefer very bold and contrasting colors.
We also like your red and black design option however at this point it is too simple for what we're looking for. We love that you are working with putting together the FSS in a design but we'd like to see something more detailed and unique, and maybe something that communicates lighting and lighted electrical maintenance.
Please continue to submit design concepts if you can, we really like your work and would like to see more options from you. Thank you!
