a pointer to a multidimensional array

Ok, sorry for not clearly documenting it. I've made a minimized version of the code, that gives me the error.

The Colorlight.h file

#ifndef ColorLight_h
#define ColorLight_h

#include "WProgram.h"

class ColourPalette
{
  public:
    ColourPalette();
    
    int** rybWheel;
};
#endif

The ColorLight.cpp file

#include "WProgram.h"
#include "ColorLight.h"

int _rybWheel[25][3] = 
	{ 	{ 0  , 255, 255 }, // 0
		{ 12 , 255, 255 }, // 15
		{ 24 , 255, 255 }, // 30
		{ 30 , 255, 255 }, // 45
		{ 36 , 255, 255 }, // 60
		{ 42 , 255, 255 }, // 75
		{ 48 , 255, 255 }, // 90
		{ 54 , 255, 255 }, // 105
		{ 60 , 255, 255 }, // 120
		{ 72 , 255, 255 }, // 135
		{ 84 , 255, 255 }, // 150
		{ 108, 255, 255 }, // 165
		{ 120, 255, 255 }, // 180
		{ 154, 255, 255 }, // 195
		{ 180, 255, 255 }, // 210
		{ 206, 255, 255 }, // 225
		{ 225, 255, 255 }, // 240
		{ 240, 255, 255 }, // 255
		{ 260, 255, 255 }, // 270
		{ 265, 255, 255 }, // 285
		{ 280, 255, 255 }, // 300
		{ 300, 255, 255 }, // 315
		{ 315, 255, 255 }, // 330
		{ 333, 255, 255 }, // 345
		{ 360, 255, 255 }  // 360  
	};


ColourPalette::ColourPalette()
{	
	rybWheel = _rybWheel; 
}

This will give the error below:

/Users/macbook/Dropbox/code/_arduino/libraries/ColorLight/ColorLight.cpp: In constructor 'ColourPalette::ColourPalette()':
/Users/macbook/Dropbox/code/_arduino/libraries/ColorLight/ColorLight.cpp:37: error: cannot convert 'int [25][3]' to 'int**' in assignment

Line 37 is rybWheel = _rybWheel;
