I have one Howeara lava burst and she blooms 2nd season in my house. Before I bought her I saw some photographs and loved her flowers for dazzling red colour. But I disappointed this year when I saw again she blooms with pale yellow in addition with pale red spotted flower. I don’t know what happens with her and why her face becomes so wan. From the beginning day I placed this plant with my phalaenopsis in a 60% shade house. So is there any possibility of low light or high temp.(now the temp. is 38C) and for this reason the flower having lost their original colours? What can I do for her?
I don't know what temperatures or how much light this one likes, but both can affect bloom color. Often, cooler temps will result in deeper, more saturated color.
