To make all programs have the same color themes, you can "exclude colors" from the individual program settings. When a configuration item is "excluded", the individual programs use the configuration settings in the Common program. So, if you exclude a configuration item from a program (or all programs), you need to adjust your settings the way you like them in the common program (common settings that are not specific to an individual program).
If you don't have the expert menu enabled, you press menu/tab once to get to the 6 block menu, then press menu tab again and a drop down list will appear. Use the down arrow key to scroll to the bottom of the list. When Expert menu is highlighted, press enter. A new menu should appear that gives you access to all the options the detector allows. The first option is program. Press enter. Use the down arrow key to scroll down to the Setup option. Press enter.(I forgot that item first time, sorry). Scroll down to Excludes and press enter. You are now in the Excludes dialog. The first item in that dialog box is titled Program. You can select individual programs that you want to exclude a setting (so that it uses the common program settings), or there's an option at the end that allows you to pick All programs. If you want all of your programs to have the same color settings, then you want to scroll down to (All Programs) using the down arrow key. If you only want to change the settings for individual programs, you will need to select the individual program and repeat as necessary to get the individual programs you want to change. Once you have selected the program (or All Programs), press menu/tab to get to the configuration selection box. Use your down arrow to scroll down to Configuration and press enter. Then scroll down to color and press enter to select color. Now your program (or all programs) will use the color palette specified by the common program. The default color palette for Common is the same as Coin and Jewelry (and coin and...).
If all you want to do is have the colors the same as Coin and Jewelry, then at this point, you should be done. If you want to adjust the colors more, ask, I will help with that if need be.
If all you want to do is change the color in that one program (I'm guessing hi-pro?) then you can adjust the colors by going to the expert menu, scrolling down to Configure, press enter. Then scroll down to the color theme list box (probably says custom in the program that you are wanting to change) and use the left or right arrow keys (right if it does say custom) until you get to Sunshine.
If you like the colors in the program, but want to change only the frequency colors, then go to expert menu/configure and scroll down to the color theme selection box. Use the right arrow to select Setup. Then scroll down to Live Search screen, press enter. Scroll down to graphic box and press enter. Scroll down to color and press enter. Scroll down to Signals and press enter. Scroll down to 2.5kHz and press enter. The first bar is how much red to have in the line, the middle bar is how much green to have in the signal and the 3rd bar is how much blue to have in the signal. If there is any red showing in the first bar, scroll down to the first bar and use the left arrow key to remove the red. Scroll down to the second bar and use the right arrow key to put more green in your signal. Scroll down to the 3rd bar and remove all the blue using the left arrow key. Do the same for the appropriate colors for the 7.5ik and the 22.5k.
