Find the right color from a wide spectrum

[joeyone]

I wonder how i can find out the right color from a pixel

i know i can use pixelgetcolor without any problem for one specifik color code

but if i have for example a red color witch is a little bit lighter or darker

how can i find out that it is red?

is this possible to find out that a color i basically red when you dealing with a wider spectrum of red shades?

thanks in advance

The decimal value returned by PixelGetColor ( x , y [, hwnd] ) of similar colors is a similar number...

For example if a pure red return 4500000 a darker red may return 4600000... (its only an example, not the actual values)

Then you can determinate similar colors by ranges...
