--- Quote from: Heart Hacker ---less light reaches the centre because its hollow so it appears to be darker ...(thats what i thought)

Firstly, it's not hollow. It has plasma and haemoglobin too. Secondly, it's not 'darker', it's paler. If you look at what ~Vin~ posted, it is lighter from the inside and darker from the outside. Since the coloration is lesser in the centre, the amount of red light absorbed (in terms of physics, the part of light which is absorbed is the one which we see) is less than for the corners. Hence the trend in the light microscope.
