Baby Blue is hex #89CFF0, rgb(137, 207, 240). Baby blue is a pale, gentle sky blue. It is calming and innocent, and it is used far beyond nurseries in wellness and healthcare products.

Reading the baby blue color codes
The hex code #89CFF0 is three pairs of base-16 numbers for red, green and blue. 89 is 137, CF is 207 and F0 is 240, each on a scale from 0 to 255. That is why the same color is written rgb(137, 207, 240) in CSS. The blue channel is the strongest here, which is what gives baby blue its cyan character.
HSL describes the same color the way people think about it. A hue of 199 degrees places baby blue in the cyan part of the color wheel. Saturation of 77% makes it vivid, and lightness of 74% makes it a light color. HSL is the easiest format to adjust by hand: keep the hue, then raise or lower lightness to create tints and shades that stay in the same family.
For print, the approximate CMYK mix is 43% cyan, 14% magenta, 0% yellow and 6% black. Screen and print colors never match perfectly, because monitors emit light while ink absorbs it, so always proof a printed sample before committing to baby blue for packaging or stationery. See MDN's guide to CSS color values for every format browsers accept.

}A shade-by-shade guide to baby blue
The 50 to 950 scale above follows the same structure as Tailwind's built-in palettes, so each step has a natural job. The lightest steps, 50 (#DEF2FB) and 100 (#C2E6F7), are page and card backgrounds: they carry the baby blue mood without competing with content. Steps 200 (#A5DBF4) and 300 (#89CFF0) suit borders, dividers, hover states and selected rows.
The middle of the scale, 400 to 600, is where baby blue is most recognizable, so use it for brand moments, illustrations and primary buttons. White text reaches the 4.5:1 body-text contrast minimum from step 700 upward, so use step 700 or darker when a button label needs to be white. Near-black text stays readable on steps 50 to 600.
The darkest steps, 800 (#3C6376) through 950 (#1D3845), make headings, body text and dark-mode surfaces that stay clearly related to baby blue. Using step 900 or 950 for text instead of pure black is one of the simplest ways to make an interface feel designed rather than default.
Colors that go with baby blue
How the baby blue color combinations work
Complementary. Directly across the color wheel from baby blue is #F0AA89, which sits closest to dusty rose among common named colors. Complementary pairs create the strongest contrast of hue, so use the second color sparingly, for a single call to action or highlight, rather than in equal amounts.
Analogous. #89F0DD and #899CF0 sit 30 degrees either side of baby blue. Analogous palettes feel calm and cohesive because the colors share undertones; they are ideal for illustrations, gradients and backgrounds where you want harmony more than contrast.
Triadic and split complementary. The triadic set (#F089CF and #CFF089) is evenly spaced around the wheel and feels playful; the second color is closest to hot pink. The split complementary set (#F0899C and #F0DD89) keeps much of the complementary contrast but is easier to balance, which makes it a good choice for data visualization and multi-category tags.
Monochromatic. The monochromatic set runs from #DBF0FA to #1A96D0. A single-hue palette is the safest way to build a calm, premium interface: rely on lightness for hierarchy, then add one neutral and one accent if you need emphasis.
Baby Blue compared with similar colors
sky blue (#87CEEB) is about as light and more muted, and shares almost the same hue. Choose sky blue if you need more weight and contrast; choose baby blue if you want its specific balance of brightness and color.
powder blue (#B0E0E6) is lighter (80% vs 74% lightness) and more muted, and leans back the wheel toward cyan. Choose powder blue if you want a softer, airier version; choose baby blue if you want its specific balance of brightness and color.
electric blue (#7DF9FF) is about as light and more saturated, and leans back the wheel toward cyan. Choose electric blue if you want a softer, airier version; choose baby blue if you want its specific balance of brightness and color.

Using baby blue in UI: buttons, text, backgrounds and dark mode
- Buttons. White labels on baby blue only reach 1.71:1, so use dark text (12.25:1 with black) or a deeper shade for the button.
- Text. Avoid baby blue for body text on white; use step 700 or darker for links and headings that need to read as baby blue.
- Backgrounds. Use steps 50 and 100 for large areas and keep the base color for smaller surfaces. Big blocks of a vivid light color draw attention, so give them a reason, like a hero section or pricing highlight.
- Dark mode. Steps 900 and 950 make a dark surface tinted with baby blue. On dark backgrounds the base color often needs a lighter step (300 or 400) to keep enough contrast for icons and borders, as required by WCAG non-text contrast.
- States. Shift one step darker for hover and two steps darker for pressed. Keep focus rings in a contrasting color so keyboard users can always see them.
Contrast and accessibility
AA needs 4.5:1 for body text and 3:1 for large text. AAA needs 7:1.
Color contrast is measured as a ratio from 1:1 (no contrast) to 21:1 (black on white). Baby Blue scores 1.71:1 against white (Fail) and 12.25:1 against black (AAA). The WCAG 2.1 contrast guideline asks for at least 4.5:1 for normal text and 3:1 for large text, which is why the shade guide above recommends specific steps for text and labels.
Contrast is only half of accessibility. Around 1 in 12 men and 1 in 200 women have some form of color vision deficiency, so never use baby blue alone to signal meaning such as success, error or selection. Pair it with an icon, a label or a change in weight.
What baby blue means
Blue is the most trusted color in digital products. It signals stability, competence and calm, which is why banks, SaaS tools and health platforms default to it.
Baby blue is a pale blue traditionally associated with baby boys in the West, though that association only became common in the 20th century. Today it is used widely for calm, gentle products.
Because so many products already use blue, the shade matters more than the hue. Pair it with an unexpected neutral or accent so the interface does not look like every other dashboard.
