Colordot

Colordot is a practical color picker tool designed to help users select, preview, and record colors efficiently through intuitive mouse or touch gestures. Unlike traditional color pickers that rely on sliders or numerical inputs, Colordot allows users to adjust hue, saturation, and lightness by moving the cursor in different directions: moving the mouse left or right changes the hue, moving up or down adjusts lightness, and scrolling with the mouse wheel modifies saturation. This gesture-based interaction makes color selection fast and natural, especially for designers and developers who need to quickly iterate color choices during visual work. The core interface displays the current color as a large, solid rectangle, with the hexadecimal code (e.g., #40BFBF) shown prominently. Users can click on the rectangle to save the color to a palette that appears below, allowing multiple colors to be captured and referenced later. The saved palette is persistent within the session, making it easy to compare colors side by side. Additionally, the tool provides a "Back & Forth" gesture hint, indicating that horizontal movement adjusts hue in a smooth, continuous manner, while vertical movement controls lightness from dark to light. The scroll adjustment for saturation gives fine-grained control over the intensity of the color. Colordot also offers a dedicated iOS app, which replicates the same gesture-based color picking experience on mobile devices. The app is available for download via a link on the website, described as "Colordot for iOS" with a call to "Get the iPhone app." This extends the functionality to touch screens, where users can use finger swipes and gestures to select colors on the go.
