Final answer:
To enter a hex code in Photoshop 2022, select the Foreground Color box, open the Color Picker, locate the hex field, and type in your desired hex color code. Press Enter or OK to apply the color.
Step-by-step explanation:
Make sure that your hex code corresponds to the specific color you wish to use. You can also use the hex code to set the background color by selecting the Background Color box rather than the Foreground Color. Additionally, Photoshop allows you to save colors to a swatch, making it easier to use them again in the future.
Note: Photoshop uses the RGB color model for its hex codes, representing colors through red, green, and blue values. If your hex code is incorrect or doesn't follow this format, Photoshop may not accept it or the color might not appear as expected.
