Light. shadcn done carefully. Neutral greys, near-black actions, one blue for links, Geist throughout.
Dark. Bone serif on carbon, a ridge line across the hero and one blue point at its summit.
Light. Bone paper, ink pills lettered in mono capitals, and a soft violet to amber aura where it counts.
Light. Cream paper, black ink, wide geometric headlines. Every section is a ruled block and every action a pill.
Dark. Black drafting table, dashed frames, mono labels and one periwinkle pen. Every section reads like a drawing.
Light. Sage drafting paper, wide squared headlines, tall orange capsules and dark product screens.
Light. Cream canvas, saturated clay tiles, chunky rounded headlines and soft pill buttons. Warm, not grey.
Light. White canvas, black type and one electric blue. Mono labels, hairline bar maps and no shadows.
Light. Hairlines, not shadows. Black buttons, one electric blue, and small tags with a pop of pastel.
Dark. Pure grey, ruled with hairlines and split down one rail. Square panels, tracked caps labels, one bright cyan.
Dark. Warm near-black, one loud orange slab, dashed rules pinned with square ticks, and pills for every control.

Light. White panels float on warm ivory: a capsule header, black pill buttons and coral kept to small marks.
Light. A pastel dawn over lavender paper: violet ink serifs, pill buttons and a few sketched stars.
Light. Every edge is a hairline, every corner is square, every headline is a serif. Colour only means status.
Light. Warm paper, light black type and one highlighter yellow that marks what matters.
Light. Big serif headlines on sunlit cream, black pill buttons, and sage leaves growing around your product.
Dark. Pure black, white grotesque type, 1px hairlines, and one magenta cloud behind the product.
Light. A quality broadsheet on cream paper. Serif everywhere, black rules, square corners, one yellow button.
Light. Serif headlines on white paper, a grainy peach haze, black pill buttons and product sheets that float.
Light. Heavy black headlines on peach paper, black buttons, one ember accent and hard block shadows.
Light. Cream paper, plum ink, one pale lavender button. Ruled in warm hairlines, labelled in mono caps.
Dark. Cream type on a midnight console, an ember and mint pill pair, and a six hue waveform under the hero.
Light. A light blue serif, mono keycaps and a drafting frame on warm graph paper. Reads like a technical manual.
Dark. Warm black bands, bold white Inter and one lime button, with a caret blinking after the headline.
Light. Warm paper, black ink and a light slab serif. Hairlines instead of shadows, rust only as text.
Light. Buttercream pages cut by five sunset stripes, with monumental wide caps and pixel labels on pill buttons.
Dark. Serif headlines, mono labels and hairline rules on near-black, with one acid lime for the thing that acts.
Dark. Pitch black and flat, with violet gradient panels, white pill buttons and a hot magenta spark.
