How to fill a color in Adobe Photoshop or Illustrator CS3

I have an PNG image that has literally thousands of like colored dots on a page it is the outline of the worlds continents. How do I change the dots globally on the image to the following color. The image opens in RGB but none of a previously dictated answer worked. I tried it all. What I want to do is be able to change the color of all the dots to either Orange White or Blue.
I was able to use the HUE  tool to Cntrl+U to get some of the colors close and that has sufficed for now. However if I can get the steps on how to convert all the dots to the Orange color below. I am sure I can get the others correctly.

In RGB the color is 244-119-33
In RGB Web the color is #F47721
In CMYK the color is 0-66.27-100-0 in that order.
Can someone look at that. I have tried everything I was told to do from a previous question and only the HUE portion actually worked partially. Please advise.

Open the file in Photoshop and in the Layers panel click the square next to the word Lock:

This is the Lock Transparent Pixels button.

Now choose Edit > Fill and choose Colour from the dropdown menu. Select the colour you want and click OK
