🎨Design Tools

Design tools for color work, icon and asset preparation, depth-of-field math for photography that crosses into design, and the small format conversions that come up daily on a creative team. Color tools cover the standard formats (HEX, RGB, HSL, HSV, CMYK) with auto-detection on input so the converter does not need a manual mode switch, plus a color wheel that builds complementary, analogous, triadic, and split-complementary palettes from a chosen base. Icon and image utilities convert single images into multi-resolution ICO files and combine source PDFs into print-ready output. The common assumption that hurts brand work is that an RGB value and a CMYK value can be exact equivalents; they cannot, because the gamuts are different, which is why the Color Converter shows both an in-gamut approximation and a flag when the conversion would not survive a print run. If you are new to the category, start with the Color Picker for any time you need to grab a color quickly, the Color Wheel Tool when you are building a palette from scratch, and the ICO Converter when a project needs a real Windows-format icon rather than a PNG renamed with the wrong extension. Photographers, designers shooting product, and anyone working with macro setups should look at the Macro Depth of Field Calculator before a shoot, not after.
