i need a logo for our Sharepoint that we will use in the company to store standards, templates, policy, information sharing. we do audio-visual, IT, and security design engineering. We are calling the sharepoint "The Vault". We want the logo to feel vault related and represent the work we do in a subtle way. Our corporate colours are indigo, white, black, and green (highlight). use #2e3166 for the background. Use green colour #009756 in a subtle way.
