Light orange, eh? I know of two tests for chlorine level, OTO and DPD, and neither should be orange. Try to find a pool store near you that does pool testing, they can do a full test and give you advice. If you're using test strips that are older than a year or test drops that are older than 2 years or have been left outside in extreme heat, sun, or cold, they could have gone bad, and may need to be replaced.
It's possible that, if the chlorine level is usually yellow, then the orange is indicating a high chlorine level. I've never seen it happen, but I don't use that type of test often. If that's the case, then you should not swim in the pool for a while, until your chlorine level is back to yellow, and possibly look for the chemical "thiosulfate" or "chlor neutralizer" or "chorine remover" - that can bring an excessively high chlorine level back down.

Do you mean that adding a little chlorine made the reading go from 0 to a higher level? You should shock your pool once a week with 1L of liquid chlorine per 10000L of water in your pool. You need to add enough chlorine to break apart the combine chlorine (the combination of chlorine and dirt which doesn't sanitize.) If you don't add enough at once, it will be used up and the chlorine reading will remain low.

Check engine light? Usually indicates a problem in the emission control system - have vehicle scanned to determine the problem
On an Acer laptop, the blue light typically indicates that the device is powered on and functioning normally. The orange light usually signifies that the laptop is in sleep mode or that the battery is charging and may also indicate a low battery level. If the orange light is blinking, it may indicate a problem with the battery or charging system. Always refer to the specific user manual for your model for accurate information.
The orange fuel tank light on the dashboard of a 1992 Toyota Land Cruiser indicates that the fuel level is low and you should refuel soon. It's a warning to prevent you from running out of fuel completely. If the light remains on after refueling, it may indicate a problem with the fuel gauge or sensor. Always check the fuel level and ensure the tank is filled to avoid potential engine performance issues.
