So as the title implies; I am colorblind (and before anyone asks, no I dont see in black and white. Yes I can see the red,yellow and green of a traffic light. Essentially my problem is seeing the differences in slight variants of similar colors). So because of this I have trouble reading my water test results. I can see that the ammonia is a yellowish green, the nitrite is a bluish purple and the nitrate is orange
. But I have a hard time telling the difference between say .50 and 1 ppm ammonia or .25-.5 ppm nitrite and so on.
How does everyone compare their test tubes to the API color chart? Do you hold the tube close to but not touching the card? If so do you hold it in front of the white section and next to the colors or directly over the colors? Or, do you hold it so its touching the card; and if so again do you hold it over the white section or directly over the color?
