Indigo to Cyan Gradient — CSS, Hex and Angles
Tech-blue plus electric cyan — the most common data-viz pair after blue to purple. The pair is #4F46E5 → #06B6D4, and on a 135° axis it reads as a diagonal wash. Everything below is generated from those two values, so the CSS you copy is exactly what the previews render.
Copy the CSS
.gradient {
background: #4F46E5; /* fallback for old browsers */
background: -webkit-linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%);
background: -moz-linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%);
background: linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%);

background: '#4F46E5', // fallback
backgroundImage: 'linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%)',
};The two endpoints
| Name | Hex | RGB | HSL | vs white | vs black | |
|---|---|---|---|---|---|---|
| Indigo | #4F46E5 | rgb(79, 70, 229) | hsl(243, 75%, 59%) | 6.29:1 | 3.34:1 | |
| Cyan | #06B6D4 | rgb(6, 182, 212) | hsl(189, 94%, 43%) | 2.43:1 | 8.65:1 |
The midpoint is #2b7edd (rgb(43, 126, 221), saturation 72%). Close to the 85% the two ends average, so the transition stays saturated throughout.
What each angle does
| Angle | Direction | Function value |
|---|---|---|
| 0° | bottom → top | linear-gradient(0deg, #4F46E5 0%, #06B6D4 100%) |
| 45° | bottom-left → top-right | linear-gradient(45deg, #4F46E5 0%, #06B6D4 100%) |
| 90° | left → right | linear-gradient(90deg, #4F46E5 0%, #06B6D4 100%) |
| 135° | top-left → bottom-right | linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%) |
| 180° | top → bottom | linear-gradient(180deg, #4F46E5 0%, #06B6D4 100%) |
| 225° | top-right → bottom-left | linear-gradient(225deg, #4F46E5 0%, #06B6D4 100%) |
| 270° | right → left | linear-gradient(270deg, #4F46E5 0%, #06B6D4 100%) |
| 315° | bottom-right → top-left | linear-gradient(315deg, #4F46E5 0%, #06B6D4 100%) |
The same pair as linear, radial and conic
| Type | Function value |
|---|---|
| linear | linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%) |
| radial | radial-gradient(circle at 50% 50%, #4F46E5 0%, #06B6D4 100%) |
| conic | conic-gradient(from 0deg at 50% 50%, #4F46E5 0%, #06B6D4 100%) |
Frequently asked
What is the CSS for a indigo to cyan gradient?background: linear-gradient(135deg, #4F46E5 0%, #06B6D4 100%); — #4F46E5 at 0% and #06B6D4 at 100%, on a 135° axis. Swap 135deg for to right if you want the direction to follow the element ratio instead of a fixed angle.
Does it need vendor prefixes?
Not for current browsers. Unprefixed linear-gradient has been supported everywhere for years, and the -webkit- / -moz- lines only matter for stacks that still ship to browsers older than 2013. The generator emits both, plus a solid #4F46E5 fallback.
Why would the middle look muddy?
This pair does not: both ends are close enough in hue that a straight sRGB blend stays clean, with mid #2b7edd holding 72% saturation against 85% at the ends.
Can I put text straight onto it?
Check both ends, not the average. White text clears 4.5:1 against the indigo end and black text clears it against neither end. Measured ratios: Indigo is 6.29:1 on white and 3.34:1 on black; Cyan is 2.43:1 on white and 8.65:1 on black.
