Colours play an important role in how we perceive and interact with the world around us. The colours we see are determined by the different wavelengths of light that are reflected off objects and enter our eyes. Orange is a vibrant, warm colour that occupies the space between red and yellow on the visible spectrum of light. It has come to be associated with energy, warmth, and vibrancy in design and culture. But how is the colour orange generated digitally on screens and in design programs? The specific colour code used to produce orange enables this vibrant tone to be recreated accurately across different mediums and platforms. Understanding colour codes like the one for orange allows designers to precisely select, manipulate, and harmonise colours in any visual medium.
What Determines The Colour Orange?
The specific shade we perceive as orange is determined by a mix of wavelengths in the visible light spectrum. The longest wavelengths we see are perceived as red while the shortest are seen as violet. Orange wavelengths are around 585-620 nanometres long. When light in this range enters our eyes, our visual system interprets and processes this as the colour orange. Slight variations in the exact mix of wavelengths generates different shades of orange. A higher concentration of longer red wavelengths makes a red-orange while more shorter yellow wavelengths give a yellow-orange. The specific orange colour code allows the precise wavelengths for different desired shades of orange to be recreated digitally on screens and in design programs.
Use of RGB & Hex Codes
On digital displays and for digital design, orange and other colours are defined using RGB colour codes. RGB stands for the three primary colours red, green, and blue. Pixels on digital screens display these three colours in different combinations and intensities to generate all the colours we see. The level of red, green and blue light is defined on a scale from 0 (no colour) to 255 (maximum colour intensity).
By mixing different intensities of these coloured lights, any hue can be reproduced digitally. The RGB code for a colour specifies the intensity of each component. For example, pure red would have an RGB code of (255, 0, 0). The values represent the red, green and blue levels respectively.
RGB codes are commonly represented in hexadecimal format as six digit codes from 000000 to FFFFFF rather than decimal 0 to 255. The two digits represent the red, green and blue components. For example, pure red in hex code is FF0000.
RGB Code for Orange
The RGB code used to generate a pure vivid orange is:
RGB: (255, 165, 0)
Hex: #FFA500
This mixes the maximum red intensity (255) with a medium intensity of green (165) and no blue (0). The balance of primarily red and green wavelengths generates an orange colour while the high intensity makes it bold and vibrant.
Slight variations in the RGB values will alter the exact shading and saturation of the orange:
| RGB Code | Hex Code | Orange Variation |
|---|---|---|
| (255, 140, 0) | #FF8C00 | Dark orange |
| (255, 165, 0) | #FFA500 | Vivid orange |
| (255, 190, 0) | #FFBE00 | Light orange |
Use in Design Programs
Design programs like Adobe Photoshop or Illustrator allow users to specify colours in RGB hex codes. This means the vibrant orange tone can be precisely selected by inputting the hex code #FFA500 into the colour picker tool. The software translates the code into the correct mix of red, green and blue light to accurately recreate that shade of orange digitally.
Designers can quickly sample colours from images and get their hex codes to reuse that exact shade. Or manually adjust the RGB values to create custom colours. This gives designers advanced control and consistency in using and manipulating colours across projects and mediums.
Web Design
In website HTML and CSS code, colours can be defined using either RGB or hex codes. This allows web designers to control colours precisely across different browsers and devices. Defining the orange header text as #FFA500 in CSS ensures it displays consistently as the same vibrant orange to all website visitors.
Hex codes are commonly used over RGB values in web design as they provide the same colour information in a more concise format. The six digit hex code is easier to quickly parse and identify when coding compared to RGB’s three comma-separated integers.
Use in Office Software
The hex code for orange can also be used in office software like Word, Excel PowerPoint and more to select that exact colour for text, cells or design elements. While these programs also have colour pickers and palettes for visual selection, inputting the specific hex code allows that shade of orange to be reused precisely across documents and applications. This prevents issues with colours shifting or varying unintentionally across different mediums and programs.
Colour Consistency
Defining the orange colour code as #FFA500 in different contexts allows that specific vibrant shade to remain consistent wherever it is applied digitally. Rather than attempting to manually match colours by eye, the hex code enablespixel-perfect accuracy. This ensures the orange appears exactly the same on printed design materials, digital displays, websites and applications. Consistent use of the colour code helps strengthen brand identity and harmony in designs using orange tones.
Accessibility
Using specific colour codes also improves accessibility for people who are colour blind or have low vision. As they are not able to distinguish certain colours, standardized colour codes ensure interfaces display information in the correct colours intended by the designer. Reliance on colour palettes alone may present issues with information in colours appearing different than intended for those with vision deficiencies.
Conclusion
The specific RGB and hex colour codes that define digital colours allow designers to precisely control and manipulate colour in any visual medium. For the vibrant orange tone widely used in design, the RGB code is (255, 165, 0) and the hex code is #FFA500. Using this code across different programs, software and devices ensures the orange is displayed accurately and consistently. It enables the precise shade of orange intended by the designer to be replicated digitally wherever it is applied. Understanding and utilising colour codes unlocks powerful colour consistency and control in the digital design process.
