Want to convert an RGB colour value to a hex code in a hurry? Don't bother firing up Photoshop. You can do it directly from Google by simply searching "RGB to Hex". This little feature, uncovered by Reddit user whizzer0, allows you to explore colours across the full spectrum and easily find both hex and RGB values for them. For more advanced needs, you can click "Show Colour Values" to find HSV, HSL and CMYK values for those same colours. Your photo editor might already have tools like this built-in, but if you don't have them open this is a handy way to look up colours.
