Only one of black and white can be right. This is the one, with the number that proves it.
Make it accessible
A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.
Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #607D66 is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).
Accessibility — WCAG contrast
Contrast is symmetric, so each row covers both directions: #607d66 as text on that neutral, and that neutral as text on #607d66.

Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.
Color scale — 50 to 950
A Tailwind-shaped ramp built around this exact hex. #607d66 is pinned to step 700; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
The same eleven steps expressed in OKLCH, where equal lightness numbers actually look equally spaced. HSL ramps go muddy in the yellows and washed out in the blues; this one does not. Modern browsers render it natively — the hex ramp above is the fallback.

Surface, border, heading and body all derive from this one hue, so the screen stays coherent without a second palette.
Lightness flips, hue holds. The accent stays the anchor in both themes.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
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.
Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

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.

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

#607d66 on white scores 4.54:1, which clears AA at every size but not AAA.
What is the complementary color of #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.

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.
Is #607d66 a web-safe color?
No. The nearest web-safe colour is #666666, ΔE2000 17 away. The palette only matters for legacy displays and some email clients now.
What does the color #607d66 mean?
As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this low chroma the association is faint; it behaves more like a neutral.
What gradient works with #607d66?
The safest is same-hue elevation: linear-gradient(135deg, #7E9C84, #607d66 45%, #37483B). For more colour, a short hue run to #536C6A keeps it rich without turning muddy.
