Checking a popular free blob generator directly: shape controls like complexity and contrast are front and center, but color isn't a control at all — the output SVG uses a default fill, and changing it means opening the exported code and editing the fill attribute by hand.
SVG blob generator with color as a first-class control
A color picker sits right next to the shape sliders here — pick a color the same way you'd adjust the shape, no code editing required.
Organic blob shape generator svg, built from real bezier curves
Points are placed around a circle with randomized radii, then connected with Catmull-Rom-to-bezier smoothing for a genuinely organic outline rather than a jagged polygon.
Random blob svg download, or copy the code directly
Both options are one click away — download a standalone .svg file, or copy the raw SVG markup to paste straight into your project.
CSS blob shape generator alternative
Unlike CSS-only blob tricks that rely on a fixed border-radius percentage string (limited to a handful of distinct shapes), this generates true SVG paths, so the shape variety is effectively unlimited.
