Enter your base color, overlay color, and opacity percentage. The tool calculates the resulting color and opacity, showing exactly how colors blend when layered with transparency.
Alpha channel controls transparency (0 = fully transparent, 1 = fully opaque). RGBA and HSLA formats include alpha values, allowing colors to blend with backgrounds or other layers.
Yes! The tool can calculate cumulative opacity when stacking multiple transparent layers. This helps you predict final colors in complex designs with multiple overlapping elements.
Opacity 50% = alpha 0.5, opacity 75% = alpha 0.75, etc. The tool automatically converts between percentage (0-100%) and decimal alpha (0-1) formats for easy use.
Yes! Transparent colors blend with backgrounds, creating different visual results. White text at 50% opacity on a blue background appears lighter blue, not white. The calculator shows exact results.
Yes! The tool generates RGBA and HSLA color codes with calculated alpha values, ready to paste into your CSS. Perfect for creating overlays, shadows, and transparent UI elements.
