Primary mark
Only use black and white versions of the wordmark. The black logo is the standard. The logo should be black on light backgrounds and white on darker backgrounds.
Secondary mark
On second use, you may use the shortened N mark. The same rules apply—use the black mark on light backgrounds (this should be the standard), and the white mark on dark backgrounds.
Design note: Other brand colors can be used with the N mark. Consult with the brand team at brand@ntara.com before execution.
