How to define a GRB?

How can I define a GRB?

I can see the scramble stuff in there but can't figure out how to define it from the maze of templates.

Unfortunate not possible to do that easy. Main problems is keep conversion from RGB-like model to others and keep instance declaration like color::rgb\<double> to be simple. Similarly from HSL we can make LSH. This will introduce more problems in implementation and make confusion in code reading. Possible idea is color::model\< rgb_scramble\<double, 1,0,2> >, downside is that this will introduce new class in currently too large API. Still thinking about that. rgb_scramble is not part of API, just idea. Best I can do is to redirect to boost::gil, it might help.

I managed it by copying from a compiler warning...

using CGRBA = color::model<color::category::rgb<color::category::_internal::rgba_scramble<unsigned char, 1, 2, 0, 3> > >;

works fine. I can cast an array of these to uint32_t* then read the uint32_t's which are in the correct 24bit order for converting into a DMA buffer for PWM to drive WS2812B LED strips.
