Bromothymol Blue (which acts as an indicator to show if photosynthesis is occurring). Bromothymol blue works because it is able to detect the presence of . CO2 (needed for photosynthesis) and . O2 (released during photosynthesis) in solution. In a test tube, you will see that: bromothymol blue + CO2 = green color. bromothymol blue + O2 = blue color
