There are several reasons why an orchid's leaves would turn yellow, unfortunately. It would be very difficult to give you a direct answer without knowing the conditions that are provided for your plant, but I will give you the most common problems for orchid issues.

Underwatering, and overwatering can both cause yellowing leaves. They should be kept in an orchid mix, or they should be affixed to a tree. They will not do well in soil and will be overwatered. If the roots are not kept moist, but not wet in an orchid mix, then it will cause these symptoms as well.

Not enough fertilizer will cause yellowing. They need to be fed at least once per month with a half strength orchid fertilizer, or a VERY VERY weak all purpose plant food solution (Not recommended since it is really easy to burn them)

Overfertilization can cause yellowing and then browning. Make sure to feed them according to the orchid fertilizer packaging to avoid this.

too much, or too little light will cause yellowing. Usually, yellowing is more common with a lack of light, but too much light will cause bleaching and burn.

They should be kept in bright but indirect light.

Humidity will be important, too. They need quite a bit of humidity to remain happy.
