You found an identity to steal. A theme that you can dive deep into and extract a visual story from. Now, your goal is to use these elements coherently. So much so, that even if your company's logo is absent from a piece of collateral, an ad, or website, it should still be recognized as something from you. Note, every design deliverable is different and the medium you are building within can have a major impact on how you will apply the visual identity. That being said, these are the top things to be aware of for cohesion:
I cannot overstate the value of a unified color palette, especially if you've selected on unique to your market. Keeping your colors intact and uniform makes your company appear more organized and it helps establish a subconscious connection between you and the selected color. When cigarette advertising became prohibited, Marlboro paid bars to paint entire walls of their spaces Marlboro red. Their sales increased as a result. That's just from establishing a brand color. Or think about Tiffany Blue and the associations of prestige that come along with it. Color has major impact.
Of all the visual elements startups get wrong, this is most common. Type is both science and art, hell, some people dedicate their entire lives to the study and creation of beautiful letterforms. Point being, it ain't easy. But there are some overarching principles one should consider. Firstly, limit yourself. Pick two typefaces max and stick to them. Secondly, choose typefaces that are legible and timeless. No curly q's or any of that Microsoft WordArt shit that sends you back to 2nd grade. If you follow those two steps, your visual prowess will be 50% ahead of anyone not doing so.
Layout is the arrangement of elements on a design deliverable. Here is what you need to decide: does your brand reflect order and cleanliness or chaos and creativity? Both are good, but you need to pick one side. By establishing a game plan for how you will layout design elements, you can create templates for websites, presentations, ads, etc and they will all bear the same amount of order. If you bounce back and forth between hyper-create and hyper-structured you lose cohesion.
Subsequent Design Elements
This is where your stolen identity comes into play the most. Brand identities need spice, transcendent elements that make them unique. Let's say you decided to steal your visual identity from a Brooklyn pizza parlor. You know, a real-deal shop with red and white table cloths, twine-wrapped wine bottles, boisterous families talking across the table, Italian flags everywhere, and old-time, sepia-toned photos of the city. That is a treasure trove. You've got patterns (tablecloth), illustrations (of cool stuff like twine-wrapped wine bottles), voice and tone (boisterous families), photo styling (sepia-tone photos) all from one unified source. The same would apply to motion graphics (maybe a pizza being tossed in the air), icons, or any other element.
If you refuse to use the clichè icons, illustrations, and photos present within your industry and replace them with something out of context, you can make something impactful. You can tell a better story. It's all in your stolen identity. Unlock that treasure trove and create something awesome!
A brand identity is the elements that make up a brand's manifestation in the tangible world; things we can see, touch, smell, taste, and hear. It's commonly limited to a logo, and while a logo is an essential piece, it's the tip of the iceberg. What lies beneath the surface is what gives it the ability to rise above the surface.
Defining the brand
The entire purpose of brand identity is to have tangible manifestations of the gut feeling you intend people to have about your business. So, you must first define it. This is done through a brand discovery. If done right, these collaborative sessions between a branding expert and client unearth the business' values, story, voice and tone, purpose, and how they are different from their competitors.
Auditing the brand
Upon defining the brand, the branding expert and client will go through the current branding efforts of the business and check for alignment. This involves everything from marketing collateral, stationery, social media posts, email newsletters, the name of the company, even the services and pricing are on the table. The key is that regardless of the touchpoint, all elements must point to the defined brand. Anything misaligned is put up for redesign.
Brand Identity Design
This is where the foundation of the brand's look is laid. It involves the creation of a name (if needed), a logo, color palette, typography, photo styling, illustration and pattern examples, and iconography.
With the core elements of the brand identity laid out, marketing collateral, a website, and other touchpoints can be created without looking scattered.
Here's where this goes wrong: when you try to build the top of the iceberg without giving it the support it needs.
You would not prescribe a cancer patient to use a band-aid as appropriate treatment.
Likewise, it'd be stupid to prescribe a logo to fix a broken brand.
You have to be willing to undergo massive overhaul to make massive change. Dive deep into the fundamental flaws of your startup. Things like being aimless, having no defined culture, no spirit, a lack of confidence or purpose. Once those are fixed, everything else becomes easier.
Don't think a band-aid will cure cancer.
