Yes, daylight definitely helps! Good tip!AndyVE said:I sometimes look into the vile when putting it on top of the test paper...
shifting it over the colours and looking for where the difference is the least.
Always use daylight though...artificial light makes it more difficult to compare.
That helps tons!WhoKnows said:I am red/green color blind. I eventually learned to read the API kit pretty well with the help of a "normie" with good color vision. The colors in the test tubes don't match up exactly with the colors on the chart. Read on a white background, and keep at it. You'll get more comfortable with it as time goes on and you read more different colors.
