Green is a color that is located between blue and yellow on the visible spectrum. It is associated with nature, health, and vitality. In web design and computer graphics, colors are often represented using hexadecimal code. Hexadecimal is a base-16 number system that uses 16 distinct symbols (0-9 to represent values 0 to 9, and A-F to represent values 10 to 15). In hexadecimal, green colors are represented by mixing together amounts of red, green, and blue. But what exactly is the hexadecimal code for the color green? Keep reading to find out.
Understanding Hexadecimal
Hexadecimal is a base-16 numbering system often used to represent colors in digital applications. While the normal decimal number system uses 10 digits (0-9), hexadecimal uses 16 distinct symbols (0-9 and A-F). This allows a single hexadecimal digit to represent a value between 0 and 15, while a decimal digit can only represent 0 to 9.
Some key things to know about hexadecimal:
- Uses 16 distinct symbols: 0-9 and A-F
- Each digit represents a value 0 – 15
- Letters A-F correspond to decimal values 10 – 15
- Two hexadecimal digits can represent 0 – 255
- Hex values are prefixed with 0x (e.g. 0xFF)
Hexadecimal provides a convenient way to represent binary values in a more compact form. Since each hex digit corresponds to 4 binary digits (bits), hexadecimal is useful for displaying colors which are typically specified by mixing amounts of red, green, and blue.
Representing Colors in Hexadecimal
In computers and on the web, colors can be represented using varying amounts of red, green and blue light. This is known as the RGB color model. By mixing together these three primary colors, many other colors can be represented.
Each RGB component is assigned a brightness value from 0 to 255, corresponding to how much of that primary color is included. In hexadecimal, these components are represented using two hex digits ranging from 00 to FF.
For example, pure red in RGB has a red value of FF, green value of 00, and blue value of 00. This can be written as the hex triplet:
FF0000
The two digits for red, two digits for green, and two digits for blue allow the representation of 256 x 256 x 256 = 16,777,216 possible colors.
Hexadecimal Green Colors
When representing a shade of green in hexadecimal RGB notation, the green component will have the highest value, while red and blue stay low.
Here are some examples of green colors in hex:
| Color | Hex Value |
|---|---|
| Lime green | 00FF00 |
| Green | 008000 |
| Dark green | 006400 |
| Light green | 90EE90 |
As you can see, a green hex value is formed by having a medium-high green level, low red level, and low blue level. Adjusting the brightness of the green component allows darker and lighter shades of green.
There are many online tools available to easily pick any green shade you want and get its hexadecimal code. Just search for “green color picker”.
Other Green Color Systems
While hexadecimal RGB values are commonly used for displaying colors in digital applications, there are a few other color models to be aware of:
- HTML Color Names – A set list of 140 colors referred to by name such as “ForestGreen” or “LimeGreen”.
- CMYK – Used for print design, mixes percentages of Cyan, Magenta, Yellow and Black ink.
- HSL – Specifies color using Hue, Saturation and Lightness values.
Hexadecimal RGB values have the widest support and are the most web-centric way to specify colors, but any of these systems have certain use cases. Converting between color models is possible using color tools.
Psychology of Green
Green has some interesting psychological and symbolic associations:
- Balance – Green balances both warm colors and cool colors, providing harmony.
- Nature – Green is strongly associated with the natural environment like forests, grass and plants.
- Growth – It represents renewal, growth and fertility.
- Peace – Green evokes calmness and relaxation.
- Health – It is often used in medical settings for its associations with healing.
- Envy – The expression “green with envy” links it to jealousy.
- Inexperience – Calling someone “green” can mean they are inexperienced.
- Wealth – The green of money and its association with wealth.
Product designers and marketers will carefully select shades of green to convey desired feelings and meanings to customers. Lighter greens tend to feel more relaxing, while very dark greens can represent prestige and prosperity.
Uses of the Color Green
Green is ubiquitous across many industries and design applications:
- Nature – forests, fields, plants
- Personal Care – soaps, cosmetics, health foods
- Healthcare – hospitals, dental offices, pharmacies
- Finance – banks, accountants, money
- Food/Beverage – organic foods, teas, catering
- Retail – relaxing, natural feel
- Technology – environmentalism, “green” tech

Green in Web Design
On websites and apps, green is commonly used for:
- Highlighting important text/calls-to-action
- Indicating success messages
- Showing progress meters
- Displaying green/eco-friendly products
- Providing a natural, organic look and feel
Dark green text provides good contrast against white backgrounds. Brighter greens bring energy but should be used sparingly to avoid eye strain.
Some examples of green in web interfaces:
| Preview | Description |
|---|---|
|  | Green buttons draw attention for important actions like signing up or purchasing. |
|  | Green success icons indicate a task was completed successfully. |
|  | Animated green progress bars show something is loading. |
The psychological associations with green work well for reinforcing positive actions and status messages.
Conclusion
Green is represented in hexadecimal RGB values by having high green component values from 00 to FF, and low red and blue values. Shades of green are formed by adjusting the brightness of the green component. Beyond hexadecimal, green can also be specified using HTML color names, CMYK, HSL and other color models. Green has strong associations with nature, growth, healing, wealth and more. It is widely used across industries including healthcare, finance and technology. On the web, green indicates positive status and encourages users to take action. The next time you come across green in a website, product or graphic design, you’ll know exactly what that shade means in hexadecimal!
