RGB32 is a 32 bit color format. It is like RGB24, except that every pixel has an additional byte to store an alpha value. An alpha value describes the transparency of the pixel. Therefore, every pixel consists of 4 bytes.
16-bit RGB (also known as RGB565)
It utilizes a color palette of 32×64×32 = 65,536 colors. Usually, there are 5 bits allocated for the red and blue color components (32 levels each) and 6 bits for the green component (64 levels), due to the greater sensitivity of the common human eye to this color.
Usually, RGB, grayscale, and CMYK images contain 8 bits of data per color channel. That is why an RGB image is often referred to as 24-bit RGB (8 bits x 3 channels), a grayscale image is referred to as 8-bit grayscale (8 bits x channel), and a CMYK image is referred to as 32-bit CMYK (8 bits x 4 channels).
Like 24-bit color, 32-bit color supports 16,777,215 colors but has an alpha channel it can create more convincing gradients, shadows, and transparencies. With the alpha channel 32-bit color supports 4,294,967,296 color combinations.
RGB24 is a 24 bit color format. Every pixel is represented by 3 bytes, while every byte of this triple corresponds to one color value. The letters 'RGB' mean Red, Green and Blue, so one byte represents the red value, one byte represents the green value and the last byte represents the blue value.
Full RGB color requires that the intensities of three color components be specified for each and every pixel. It is common for each component intensity to be stored as an 8-bit integer, and so each pixel requires 24 bits to completely and accurately specify its color.
8-bit files have 256 levels (shades of color) per channel, whereas 16-bit has 65,536 levels, which gives you editing headroom. 32-bit is used for creating HDR (High Dynamic Range) images.
This means that each of the RGB channels has 256 shades so there are 256x256x256 or 16,777,216 colors in total in this 8-bit RGB system. An 8-bit color system is capable of producing over 16 million colors. This may look humungous, but when it compared to 10 bit, this is actually nothing.
8-bit colour distinguishes 256 different tones, 10-bit colour distinguishes 1024 tones, and 12-bit colour distinguishes 4096 tones.
Using three bytes per pixel in a display system (eight bits for each red, green and blue subpixel). Also called "True Color" and "RGB color," a total of 16,777,216 colors can be represented in the color palette.
As each RGB pixel has three sets of 8-bit binary numbers it therefore has 24 bits of computer information in total. Hence the term '24-bit colour'. And as 8 bits equals 1 byte, each RGB pixel therefore equals 3 bytes in file size.
It really comes down to math and getting a value between 0-1. Since 255 is the maximum value, dividing by 255 expresses a 0-1 representation. Each channel (Red, Green, and Blue are each channels) is 8 bits, so they are each limited to 256, in this case 255 since 0 is included.
If you can do all of your color grading with one effect, or if you're doing more gentle adjustment, 8 bit could be just fine. But if you're relly doing a major push/pull or using several instances of color effects, 32 bit may be your best bet.
6 bit – 262 thousand colors. 8 bit – 16.7 million colors. 10 bit – 1.07 billion colors.
Up to 65,536 colors can be represented in the color palette. Most graphics formats provide 8-bit color or 24-bit color; however, graphics cards generally have an intermediate 16-bit color range that displays 65,536 colors. See color depth.
The RGB model uses 8 bits each — from 0 to 23 — for red, green and blue colors. Each color also has values ranging from 0 to 255. This translates into millions of colors — 16,777,216 possible colors to be precise.
To display black, set all color parameters to 0, like this: rgb(0, 0, 0). To display white, set all color parameters to 255, like this: rgb(255, 255, 255).
The RGB color 255, 255, 255 is a light color, and the websafe version is hex FFFFFF, and the color name is white. A complement of this color would be 255, 255, 255, and the grayscale version is 255, 255, 255. A 20% lighter version of the original color is 255, 255, 255, and 198, 198, 198 is the 20% darker color.
Most importantly, 32-bit systems are slow in computing calculations due to the amount of memory available. Due to this, they render graphics slower and at a much lower quality as compared to their 64-bit counterparts.
The first, smaller PNG is an 8-bit PNG, while the larger PNG is a 32-bit PNG. Now we know what color depths mean and how we can calculate the file size of an uncompressed image, but the data still occupies a lot of space and needs to be compressed accordingly.
A display system that provides 4,096 shades of color for each red, green and blue subpixel for a total of 68 billion colors. For example, Dolby Vision supports 12-bit color. A 36-bit color depth also means 12-bit color because the 36 refers to each pixel, not the subpixel.
RGB – Three Numbers
one each for red, green, and blue. In RGB, a color is defined as a mixture of pure red, green, and blue lights of various strengths. Each of the red, green and blue light levels is encoded as a number in the range 0.. 255, with 0 meaning zero light and 255 meaning maximum light.
Red, green and blue can be combined in various proportions to obtain any color in the visible spectrum. The RGB model uses 8 bits each — from 0 to 23 — for red, green and blue colors. Each color also has values ranging from 0 to 255. This translates into millions of colors — 16,777,216 possible colors to be precise.
RGB 0-1 is also known as "Unit RGB". This is because the values are normalized to the range of 0 to 1 (Unit), where 1 is the maximum intensity. This is different from the typical RGB representation where the values range from 0 to 255, with 255 being the maximum intensity.
The max value that can be stored in an 8 bit byte is 255 so the 256 rgb values are stored ranging from 0 to 255. Because the 24-bit code is divided into 8 bits for each color (R/G/B). There are a total of 256 numbers in the binary eight bits in the system, and the maximum value from 0 is 255.
