Mint Green and Pink Color Scheme Examples | How to Make the Boundary Between Two Pale Colors Easier to Distinguish

Mint green and pink are natural candidates when a web page calls for two gentle colors. Yet when both are very light, the boundary between them may be hard to distinguish even though their hues are different. Using a fictional registration page for a herb-and-flower workshop, this article compares two solutions: defining adjacent colored information panels and reducing the areas covered by the pastel colors.

Pale mint and pink can have different hues but almost the same lightness

For the examples, choose mint green ■#DFF3EA and pale pink ■#F9E2EA. A HEX code is a way of specifying a web color with a hash sign followed by hexadecimal digits, usually six. The contrast ratio between these two colors is only about 1.06:1. A contrast ratio measures the difference in relative lightness between colors, and a result close to 1:1 indicates very little difference.

Mint and pink belong to different hues—the green and red families—but their similar brightness means that merely placing the two areas next to each other may not make the boundary clear. Leaving a nearly white gap between them can help with grouping, but that alone does not necessarily create a strong visible outline around each pale panel.

First decide whether the colored areas need to represent separate groups of information or are merely decorative. Use spacing, borders, and headings for meaningful groups. If the colors only decorate the page, limit the area they occupy. Do not rely on hue alone to communicate a distinction.

Compare two approaches on a workshop registration page

Option 1: Place mint and pink panels side by side with visible outlines

Give the “Herb Bookmark Making” information panel a mint ■#DFF3EA background and the “Flower Card Making” panel a pink ■#F9E2EA background. Leave around 16px between the panels and, where a clearly defined boundary is useful, add an approximately 2px border in muted gray-purple ■#817780 to both. This border contrasts at about 3.72:1 with the mint and 3.50:1 with the pink, making the two shapes easier to identify without replacing the pastel fills.

Use deep green ■#315348 for the mint panel’s heading and dark reddish purple ■#4F3241 for the pink panel’s heading. Their respective text-to-background contrast ratios are about 7.37:1 and 9.17:1. For descriptions such as what to bring and the session time, use the same dark gray ■#303639 in both panels. It provides about 10.60:1 contrast on the mint and 9.98:1 on the pink. Include text labels such as “Herbs” and “Flowers” so visitors do not have to infer the subject from the background color.

Option 2: Keep the card bodies neutral and use the two colors only in header bands

When the descriptions are longer, set the page background to light gray ■#F4F2EE and both card bodies to ivory ■#FCFAF6. Reserve mint ■#DFF3EA and pink ■#F9E2EA for the bands at the top of the cards. Because the contrast ratio between the page and the ivory card bodies is only about 1.07:1, surround the complete cards with borders in ■#817780. The border contrasts at about 3.85:1 with the page background and 4.12:1 with the ivory surface.

The colored header bands can retain the same deep green ■#315348 and reddish purple ■#4F3241 heading colors as in Option 1. Put the card descriptions in dark gray ■#303639 on ivory ■#FCFAF6; this text pairing has about 11.76:1 contrast. If each card includes a “See Dates” button, use a common deep green ■#2D4944 button background with ivory ■#FCFAF6 text for about 9.38:1 contrast. Even though the headers have different colors, the same action should have the same button styling.

Check the purpose of borders and the mobile layout

The Web Content Accessibility Guidelines (WCAG) 2.2, Level AA, require at least a 4.5:1 contrast ratio for normal-size text against its background and 3:1 for qualifying large text. Visual elements essential for identifying an interface control or understanding a meaningful graphic generally require at least 3:1 against adjacent colors. That does not mean every purely decorative card border must meet 3:1. Decide whether the line conveys a necessary boundary or is simply decoration before evaluating its role.

On phones, make sure the gap and headings still distinguish the two panels when they stack vertically. Do not represent availability or selection states solely through mint and pink; add explicit text such as “Registration Open” or “Selected.” If photos or translucent overlays change the colors, recalculate contrast against the actual adjacent areas. All ratios in this article are separate calculations for the specified opaque colors, not a guarantee that an entire finished page complies with accessibility requirements.

HueRoll can take HEX codes, display lighter and darker variations and palette suggestions, and compare the selected color against white and black. It does not automatically calculate contrast between any two chosen colors or give a WCAG AA pass/fail assessment. Keep the gentle mint and pink backgrounds, and reinforce necessary boundaries with outlines, spacing, and headings so the information remains easy to organize.
