Well try this:
1. Open the Image you wish to copy the color from
2. Click on th eEyeDropper Tool on the toolbox which is on the left side of ur screen.
3. Your mouse icon would change to an eye dropper. Noe click on the area of the Image you wish to pick the color from.
4. You will notice on the left toolbox there is a square color box which changes to the color you clicked on. It is on the left side bottom of the toolbox.
5. Now Click on this quare box.
6. A New window would open with the color selection options. Find a edit box which is like # __________ on the bottom of this window. Its is a six digit alphabet. Copy this alphabet. Thi sis the number you need.
Just a remark. Once you have selected the color using the eyedropper tool, the next image you open, you can use the currently selected color without even knowing the code, as it is already selected.
Let me know in case of any doubt.
