About Lime

Color psychology: Energy, freshness.

Lime (#00FF00) is a medium shade of green with a hue angle of 120° on the color wheel, 100% saturation, and 50% lightness. It's commonly used in web design, graphic design, and branding where energy, freshness are desired associations.

In color theory, Lime sits in the neutral section of the spectrum. Its high saturation makes it vivid and attention-grabbing — ideal for CTAs, headings, and brand accents.

When to Use Lime in Design

Web Design

Use Lime for headings, links, or accent elements against light backgrounds. Dark colors like this provide strong contrast and draw the eye to important content.

Branding & Logo

Lime conveys energy, freshness — consider it for brands that want to project these qualities. Test it at small sizes (favicon, social avatar) to ensure it remains recognizable.

Print Design

Use the CMYK values (C:100% M:0% Y:100% K:0%) for accurate print reproduction in brochures, business cards, and packaging. Request a physical proof — screen colors often appear more vibrant than their printed equivalents.

UI / UX Design

Dark colors like Lime are effective for primary buttons, navigation bars, and text. Use a lighter tint (increase HSL lightness to 90%+) for hover backgrounds.

How to Use Lime in CSS

/* Using HEX */
color: #00FF00;
background-color: #00FF00;

/* Using RGB */
color: rgb(0, 255, 0);

/* Using HSL — best for creating variations */
color: hsl(120, 100%, 50%);

/* Transparent overlay (50% opacity) */
background-color: rgba(0, 255, 0, 0.5);

/* Lighter variant for hover states */
background-color: hsl(120, 100%, 60%);

/* Darker variant for active states */
background-color: hsl(120, 100%, 40%);

HSL is the most flexible format for creating color systems. By adjusting the lightness value, you can generate an entire shade scale from Lime without changing its core hue or saturation.

Frequently Asked Questions

What is the hex code for Lime?

The hex color code for Lime is #00FF00. In CSS, apply it as text color with color: #00FF00;, as a background with background-color: #00FF00;, or as a border with border-color: #00FF00;. Hex is the most widely used color notation on the web because it is compact, supported by every browser, and easy to copy between design tools like Figma, Photoshop, and code editors.

What is Lime in RGB and when should I use RGB?

Lime in RGB is rgb(0, 255, 0), where Red=0, Green=255, and Blue=0 on a 0-255 scale. Use RGB when you need transparency — rgba(0, 255, 0, 0.5) creates a 50% transparent version. RGB is also the native format for HTML canvas, WebGL, and JavaScript image manipulation, since each channel represents the intensity of that primary light color on screen displays.

How to use Lime in CSS with different color formats?

Lime can be applied in CSS using multiple formats: (1) Hex: color: #00FF00; — most compact and widely used. (2) RGB: color: rgb(0, 255, 0); — useful when calculating colors dynamically in JavaScript. (3) HSL: color: hsl(120, 100%, 50%); — best for creating variations, since adjusting lightness produces lighter or darker shades while keeping the same hue. (4) With transparency: rgba(0, 255, 0, 0.8); or hsla(120, 100%, 50%, 0.8); for 80% opacity overlays.

What is the HSL value of Lime and why is HSL useful for designers?

Lime in HSL is hsl(120, 100%, 50%). HSL stands for Hue (120 degrees on the color wheel), Saturation (100% color intensity), and Lightness (50% brightness). HSL is the most intuitive format for designers because you can create harmonious palettes by rotating the hue, generate hover effects by increasing lightness by 10%, and desaturate colors by reducing the S value. This makes Lime a medium, vivid neutral-toned color.

What is the CMYK value of Lime for print design?

Lime in CMYK is C:100% M:0% Y:100% K:0%. CMYK (Cyan, Magenta, Yellow, Key/Black) is the standard color model for professional printing — business cards, brochures, merchandise, and packaging. When designing for print in Adobe InDesign or Illustrator, use these exact CMYK values to ensure accurate color reproduction. Screen colors (RGB) often appear more vibrant than their printed CMYK equivalents, so always request a physical proof for brand-critical materials.

What colors pair well with Lime in design projects?

Green pairs naturally with white, cream, and brown tones. Dark greens work with gold for a luxury feel. In UI design, green is universally associated with success, confirmation, and positive actions.

Is Lime (#00FF00) accessible for web design and WCAG compliant?

Green text needs to be dark enough for contrast (below #2E7D32 on white). Never rely solely on red/green to distinguish states — about 1 in 12 men cannot distinguish between these two colors. For Lime specifically: as a medium shade (lightness: 50%), it can work as a text color on light backgrounds, but verify the exact contrast ratio using a contrast checker tool. WCAG 2.1 requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18px+ bold or 24px+ regular).
