  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Black text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. The low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

Transparency

What each alpha value actually composites to. The top row is #607d66 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#607d66, answered

What color is #607d66?

#607d66 is a dark muted green, closest to Sea Green (ΔE2000 11.5). It sits at 132° on the hue wheel with 13% saturation and 43% lightness, which reads as neutral.

What is the RGB value of #607d66?

rgb(96, 125, 102) — 96 red, 125 green and 102 blue out of 255, or 37.6% / 49% / 40% by channel.

What is #607d66 in HSL and HSV?

hsl(132, 13%, 43%) and hsv(132, 23%, 49%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #607d66 a light or a dark color?

It is a mid-tone. Relative luminance is 0.1811 and perceived brightness is 45%, so black text on it reaches 4.62:1.

Should I use black or white text on #607d66?

Black. It scores 4.62:1 against #607d66, versus 4.54:1 for white — AA at any size.

Is #607d66 accessible on a white background?

#607d66 on white scores 4.54:1, which clears AA at every size but not AAA.

What is the complementary color of #607d66?

#7D6077 sits directly opposite on the wheel. Softer options are the split-complements #74607D and #7D6068, which give the same contrast with far less vibration.

What colors go well with #607d66?

For interface work: #F6F8F7 as the surface, #D1DCD3 for borders, #64826A for secondary text, #805C81 as an accent and #37483B for hover and pressed states. For a palette, the analogous pair #687D60 and #607D74 stays calm, while #7D6077 is the loudest partner.

What is #607d66 in CMYK for printing?

cmyk(23%, 0%, 18%, 51%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #607d66 warm or cool?

Neutral — it scores 57 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #657D60; nudged cooler, #5E7F71.

Which Tailwind color is closest to #607d66?

The neutral family — its 500 step is #737373, ΔE2000 15.9 away. That is a visible difference, so define #607d66 as a custom token rather than reaching for the built-in.

How do I use #607d66 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#607d66] or text-[#607d66], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #607d66 with 50% opacity?

rgba(96, 125, 102, 0.5), or #607d6680 in eight-digit hex. Over white that composites to #B0BEB3; over black, #303F33.
