To change the color of an HTML input's placeholder text using CSS, you can use the ::placeholder pseudo-element selector. Here are two possible ways to accomplish this:
Method 1: Using the color property
You can change the color of the placeholder text by applying the color property to the ::placeholder pseudo-element selector. Here's an example:
input::placeholder {
color: red;
}
In this example, the placeholder text of all input elements will be displayed in red.

Method 2: Using the ::placeholder selector with a specific input type
If you only want to change the color of the placeholder text for a specific input type, you can combine the ::placeholder pseudo-element selector with the attribute selector for that input type. Here's an example:
input[type="text"]::placeholder {
color: blue;
}
In this example, only the placeholder text of input elements with the type "text" will be displayed in blue.
It's important to note that the ::placeholder pseudo-element selector is supported in modern browsers, but it may not work in older versions of Internet Explorer. To ensure compatibility, you can use vendor prefixes and the older ::-webkit-input-placeholder and :-ms-input-placeholder selectors. Here's an example:
input::placeholder,
::-webkit-input-placeholder,
:-ms-input-placeholder {
color: green;
}
In this example, the placeholder text of input elements will be displayed in green, with compatibility for different browser prefixes.

When changing the color of an HTML input's placeholder text with CSS, it's important to consider the following best practices:
1. Choose a color that provides sufficient contrast with the background color of the input element. This ensures that the placeholder text is easily readable.
2. Avoid using colors that may be associated with specific states (e.g., red for error messages) to prevent confusion between the placeholder text and actual input values.
3. Test your changes in different browsers to ensure compatibility and consistent rendering across platforms.
4. Consider using CSS preprocessors like Sass or Less to define variables for placeholder colors, making it easier to maintain and update your stylesheets.
