I´m working on a set of generative GLSL shader and I have a problem with the default value of an ISADORA_VEC4_COLOR_PARAM.

Example:

// ISADORA_VEC4_COLOR_PARAM(inside_color, isc, 0xA6D9FFFF, "The color used to fill the inside of the shape.");
uniform vec4 inside_color;

I would expect a light blue color with fully opaque.

But I got:

If I use a vec3 without an alpha channel the color is correct, test_inside_color in the image:

Is this an issue ?

Thanks
