Designer has a lot of creative freedom on this one. The name is an obvious play on words that the user of the application will have "sight" on their equipment in the "field". To the extent you can incorporate visual metaphors for one or both of those words into the logo great, but not required. Name can have space or not.
In general, we're thinking of blue as a primary color and secondary colors of gray, red, or green, but really no requirement to use those colors.
Will be used on web in small size for identity branding so should be legible at heights as small as 64 pixels, but obviously work well at larger sizes.
Please do not use any stock images or clip art in the logo
Prefer clean, simple, bold design. Interpret as desired.
