For example, try Inter. - Alternative: Try a sans serif with soft curves to echo the rounded icons. DM Sans is one option. - Editorial: Use restrained letterforms when the text should carry most of the detail. For example, try Neue Haas Grotesk. - Body: Keep text weight close to the light icon strokes. Source Sans Pro or Mulish are examples. - Caution: Expressive display type can draw much more attention than these icons. Compare examples such as Syne or Playfair Display at the final size. **Core Solid** - Primary: Choose medium or semibold text to balance the filled shapes. For example, try DM Sans Medium/SemiBold. - Alternative: Try a sans serif with soft curves in a medium weight. Plus Jakarta Sans is one option. - Body: Regular weight text can sit below heavier headings. For example, try Inter Regular. - Caution: Hairline text may look too light beside the fills. Check the weight difference in the layout. **Core Remix** - Primary: Choose simple rounded letters to balance the mix of lines and fills. For example, try Outfit. - Alternative: A restrained sans serif can keep the composition quiet. DM Sans is one option. - Body: Use plain supporting text beside the varied icon detail. For example, try Inter. - Caution: Highly expressive display letters add another point of attention. Check the balance with the icon. **Core Pop** - Primary: Rounded geometric letters can echo the icon shapes. For example, try Poppins. - Alternative: Try soft curves with enough weight to sit beside the fills. Plus Jakarta Sans is one option. - Display: Stronger letterforms can give a campaign heading emphasis. For example, try Clash Display. - Body: Keep supporting text simple beside the multicolor details. DM Sans Regular is one option. - Caution: Rigid monospace letters create a stronger contrast with the rounded forms. Check whether that contrast helps the layout. **Core Duo** - Primary: Choose simple sans serif letters that leave attention on the color accents. For example, try Inter. - Alternative: Try more structured letterforms for a firmer appearance. IBM Plex Sans is one option. - Body: Keep supporting text close in weight to the light outlines. For example, try Source Sans Pro. - Caution: Decorative serifs or very rounded display letters add another style beside the color contrast. Check whether both are needed. **Core Neon** - Primary: Try a geometric sans serif with some distinctive detail. Space Grotesk is one option. - Alternative: More compact letterforms can help where space is limited. For example, try Barlow. - Body: Use enough text weight to remain distinct beside both line colors. Inter Medium is one option. - Caution: Decorative serifs or handwritten letters add detail to an already contrasting color treatment. Check their combined effect. **Core Flat** - Primary: Simple sans serif letters can balance the two-color fills. For example, try Inter or DM Sans. - Alternative: Softer curves can echo the rounded silhouettes. Outfit is one option. - Caution: Decorative display letters can compete with the filled shapes. Keep enough space between them. **Core Gradient** - Primary: Choose simple letters that leave attention on the gradient fills. For example, try DM Sans. - Alternative: A restrained sans serif can give the layout a steadier appearance. Neue Haas Grotesk is one option. - Display: Strong letterforms can give larger headings emphasis. For example, try Syne. - Body: Keep supporting text plain. Inter is one option. - Caution: Monospace or high contrast serif headings add another strong treatment.
