Well it depends for what Spanish speaking country you want it in Spanish. Orange is the color naranja. The fruit I understand is called naranja in many Spanish speaking countries. But in Puerto Rico it is called china the sweet fruit. Naranja in Puerto Rico is the sour acid fruit. Similar in size to the orange. Not grapefruit. I am a native of Puerto Rico. In other Spanish speaking countries could happen something similar. Sincerely, Antonios
