[ft] Problem with text color

Hi All,

        With gray-scale font I am getting a buffer . Each byte in the buffer has 0 to 255 levels of gray values. I am doing raster operation using this buffer to my device screen

to draw the font. But the problem is how can I draw different colors using this gray values. I mean rgb( 0, 0, 0 ) gives black and rgb(255, 255, 255) gives white and rgb( 150, 150 ,150) gives some light black or gray color. These 0, 255, 150 are gray values of the buffer. Using the above logic I am able to draw black text, I am not able to draw other text colors. Is there any algorithm to get native color value using gray values. I mean if I want to draw with pink color rgb_new( 0, 0, 0 ) should give pink color, rgb_new( 150, 50,150)

Should give light pink color and rgb_new( 255, 255, 255) should give very light pink color. Then I will get a smooth border for the text with pink color. Please help me how to draw with different colors.
