Hows this look ?? Pic

For this test block, you can add an extra drop of the OTO and Phenol to see if it make reading the colors easier. The colors will be more saturated (darker) but the hue (color) will not be different. The extra drop may making reading it easier and it will not changes the readings.

Good job on ordering the test kit, you will not regret the investment.

I highly recommend this one.You will NOT find it in any store. TF-100
