How to get the correct RGB values (0-255) for a single gaussian?

[vitorpmh]

I was trying to visualise the gaussians individualy with matplotlib and for that i needed their colours. Found this issue but there isn't a specific solution.

I have tried to use arctan, arctanh, sigmoid, inverse of sigmoid, minmaxscaling but i couldn't find a solution that gives the correct colour.

The following is the method that i am using to provide the colours. However it returns values a weird range eg (-0.3426, 2.5341).

class GaussianImage_RS(nn.Module):
    @property
    def get_features(self):
        return self._features_dc

Could you please clarify how to get the rgb colour of a individual gaussian?

Thanks in advance.
