I find it a bit challenging as well. I either see orange when it's 7.5 or below, or a lavender color as it approaches 8.0. I try to use a light background and always do my testing outside in the shade as the natural light seems to help me distinguish between the colors. Sometimes I'll ask someone else to tell me what they think it is to help my better compare shades.I am having trouble telling the difference on the meter between 7.6 and 8.0.
