Bold Two-Tone Contrast
The black and blue rectangular optical frame combines a classic black front with vivid blue temples for a distinctive two-tone finish. The front remains clean and understated, while the colour along the sides introduces a much stronger visual contrast.
Its lenses follow a soft rectangular shape with gently rounded lower corners. The upper rim has a subtle curve rather than a completely straight brow line, helping the frame maintain a balanced silhouette. The solid black front also gives the lens openings clear definition without adding unnecessary decorative detail.
Clean Full-Rim Front
Cobalt Crest features a full-rim construction with a moderately defined black front. The rims are substantial enough to create a clear outline while remaining more streamlined than several of the heavier rectangular frames seen earlier.
The integrated bridge continues naturally from the surrounding frame material. Its centre section is compact and smooth, keeping the front visually cohesive. Slightly extended outer corners connect the lens rims to the temples without creating an exaggerated angular effect.
This black and blue rectangular optical frame therefore balances a traditional front profile with a much more noticeable side treatment.
Blue Temples with Contrasting Hinge Detail
The temples are the defining feature of Cobalt Crest. They use a bright blue finish that remains clearly visible from both the front and side angles. The blue continues along the temple length and into the curved temple ends.
Near the hinges, white cylindrical sections create a sharp break between the black front and blue sides. Slim metallic rings and visible hinge hardware add another layer of contrast. These small details make the side profile considerably more distinctive than a conventional solid-colour frame.
The combination of black, blue, white and metallic accents gives the design a layered appearance while keeping each colour clearly separated.
Distinctive Without Excess Decoration
Despite its contrasting colours, the design remains relatively clean. The front carries no elaborate patterns or prominent exterior ornamentation. Instead, the character comes from the colour transition and hinge construction.
The black front keeps the overall appearance grounded, while the bright blue temples provide the visual highlight. This makes the black and blue rectangular optical frame noticeably different from both monochrome black styles and patterned frames in the collection.
Cobalt Crest brings together a softly rectangular silhouette, full-rim construction and a strong two-tone colour combination in one clearly defined design.
