Does anybody know the regular expression code to change any thing similar to ”#f2f2f2;” in to ”#000000;”. Also the one for rgb(210, 236, 238); to rgb(0, 0, 0);. I guess you can tell that in a long text file I want to change all colors to black. I am using the Notepad++ Find and Replace box(pic). Thanks

For hexadecimal values:

Find what: #[0-9a-fA-F]{6}
Replace with: #000000

For RGB values:

Find what: rgb\(\d{0,3},\s?\d{0,3},\s?\d{0,3}\)
Replace with: rgb(0, 0, 0)

The find regex expression won’t check to see if the values are greater than 255.
