Now, this is the part where we discuss RGB, Bit Depth, and Gamut.
RGB
RGB is the primary color used in additive color mixing. It includes red, green, and blue.
By applying and combining different amounts of these colors, you’ll be able to create a wide range of colors. In adjusting the hues, you’ll be able to create millions of possibilities.
With each adjustment comes a new color. Learning the combination of these colors can help you a lot.
RGB operates on an additive principle, where the combination of full-intensity red, green, and blue results in white light.
This color model is extensively utilized in digital technology, such as computer monitors, televisions, and cameras, to accurately display and capture colors.
RGB is a color model used in various applications: digital displays, photography, and web designs use this the most.
As RGB color profiles are primarily used for computer screen applications, CMYK color profiles are used for print operations.
Bit depth

See how much you really know about photography…
Bit depth refers to the number of bits used to represent each color channel in an image.
In other words, this refers to the amount of color information stored in an image or the bits used to represent each pixel’s color.
It determines the number of possible color assignments for each pixel. A higher bit depth allows for a greater range of colors to be displayed.
For example, a 1-bit image can only display black and white, while an 8-bit image can show 256 different colors, and a 24-bit image can display over 16 million colors.
When bit depth increases, the image’s file size also increases. This is due to how much color information needs to be stored for each pixel.
You can choose the bit depth of an image when you save or export it.
The bit depth also depends on the type of image you are curating or the desired quality that you’re aiming for.
For images with few colors, reducing the bit depth can significantly reduce file size without significant quality loss, but for images with gradients or complex designs, reducing the number of colors can severely degrade image quality.
When working with ProPhoto RGB, it is recommended to use a higher bit depth, such as 16 bits per channel, to avoid posterization effects and preserve color accuracy.
Gamut
Gamut is the range of colors that can be reproduced or displayed by a device or system.
It represents the entire spectrum of colors that can be perceived or captured.
The ProPhoto RGB color space has an exceptionally large gamut, encompassing over 90% of possible surface colors in the color space and 100% of likely occurring real-world surface colors.
Gamut follows the color space RGB or CMYK, and different devices have varying gamuts.
Its variation comes in terms of the number or intensity of colors that it produces.
It’s important to consider the gamut capabilities of devices when working with color-sensitive applications to ensure a more accurate color representation in all possible devices.
Remember: A wider gamut means the device can show a larger range of colors, resulting in a much more vibrant and accurate color reproduction.
However, a narrow gamut means the range of colors is limited, which may result in a less vibrant or inaccurate color rendering.
ProPhoto RGB vs sRGB vs Adobe RGB: What’s the Difference?

When it comes to color spaces, ProPhoto RGB, sRGB, and Adobe RGB are three commonly used options.
Each color space has its characteristics and is suitable for different purposes.
Here’s a breakdown of the differences:
1. sRGB (Standard RGB)
sRGB is a standard RGB color space. Think of sRGB as a widely used display for general purposes.
It has a narrower gamut than Adobe RGB and uses 8 bits per channel, which is sufficient for general purposes.
It comes up in common devices, software, and online platforms (web display, media sharing, and viewing images) on standard monitors.
It also ensures consistent color representation across different devices and platforms, making it a safe choice for everyday use.
2. Adobe RGB (1998)
Adobe RGB color space has a wider gamut than sRGB but is narrower than ProPhoto RGB.
It’s used with higher bit depths, with 16 bits per channel. This way, it preserves color accuracy and avoids posterization effects as it can contain more colors and has a larger color range.
Yet, there are still downsides to Adobe RGB. Despite how well-supported it is, it’s not as universally compatible as sRGB.
There’s a chance that it may not display accurately on devices or platforms that do not support the Adobe RGB color space.
Adobe RGB is suitable for capturing and reproducing vibrant and saturated colors, making it ideal for high-quality prints.
As it offers a wider gamut than sRGB, Adobe RGB is also used in professional photography and printing workflows.
3. ProPhoto RGB
This offers the widest color gamut among the three color spaces.
This gives a much larger color range compared to both sRGB and Adobe RGB.
It’s commonly used in professional editing and high-end printing, where preserving the maximum amount of color information is important.
However, similar to Adobe RGB, it may not be suitable for all purposes, as it can produce colors that are outside the range of most devices and platforms, leading to inaccurate display.
What Is ProPhoto RGB Used for?
In the world of photography, editing must come with precision and control over color.
Hence, photographers use ProPhoto RGB to capture a wider range of colors to have a much more realistic image print.
