Take your photos from this:

Step 1: Open your photo in GIMP and under the Colors tab click on Hue-Saturation.

Step 2: If you try to increase the overall concentration, the clay walls become much too yellow.

To choose what colors you want to be saturated, use the color wheel above the sliders.  Click the dot next to the color of choice (here, blue) and then when you use the saturation slider it will only control the saturation for that color.

Step 3: You can make changes to the saturation of multiple different colors if you like, you do not even have to close the dialogue box in between.  If you ever want to control the saturation of all the colors, as you started, just click on the Master button.  In this photo, I increased the saturation of blue, cerulean (light blue) and red.

Step 4: If you open the Curves dialogue box, under the drop down Channel menu (it defaults to Value) you can select the different colors and control them via the Curves graph instead of controlling the overall saturation of the color by the slider only.

Step 5: Save your final image with increased saturation of select colors.
