How accurate are AI image detection tools?

AI image detection tools have improved a lot, but they aren’t perfect. They can usually identify many AI-generated images by spotting common visual clues, but sometimes they may miss subtle fakes or wrongly flag real photos.

Using tools like QuillBot’s free AI image detector alongside visual checks and source verification gives you the best chance of spotting AI-generated content accurately.

What tool can I use to generate a color palette from a hex code?

You can use a color wheel tool like QuillBot’s color wheel to generate a color palette from a hex code.

Just enter your hex code, and the tool will suggest matching color harmonies—such as complementary, analogous, triadic, tetradic, or square—that you can use as a starting point for your palette.

If you have an image containing color combinations that you think might suit your project, upload it to QuillBot’s free color palette generator to extract a balanced four-color palette based on the image.

How do you change the hue on a color wheel?

On an online RGB color wheel like QuillBot’s color wheel tool, you change the hue by moving the selector around the circle (rather than from inside to outside).

Going around the circle shifts the color family (red → orange → yellow → green → cyan → blue → purple → back to red).

How can I use a color wheel to build a palette?

You can use a color wheel like QuillBot’s color wheel tool to build a palette of colors whose hues have a color theory relationship—such as complementary, analogous, triadic, tetradic, or square colors.

Start by entering your base color (usually a HEX code). The tool will suggest related colors and provide their color codes. Then refine the palette by adjusting lightness (value), saturation, and how much of each color you use—often with one main color, one supporting color, and one or two accents.
