For to know the diversity of flower colour change check Color forms of Laelia purpurata
Typical plants (“Tipo”) have white petals and sepals, blushed pink. The pink can be lighter or darker. The lip is purple, and this purple lip is dominant in hybrids.
Concolors are always pink; they have pink lips, petals and sepals. The lip can be darker than the petals and sepals.
Whites have pure white petals and sepals, with no hint of color. Albas have pink in the throat, but not farther out in the lip. Semi-albas have purple lips. Atro has a very dark lip. Virginalis is pure white, with no hint of pink nor purple.
Blues have several forms. The coerulea we are familiar with is called Ardosa in Brazil. A brighter blue is called Roxo-violeta in southern Brazil, and Aco in the north. Werkhauserii is an unusual grayish blue that is found in no other orchid. For years it was unavailable outside Brazil, or inside, for that matter.
Carnea has a raspberry- or strawberry-colored lip. These plants used to have lighter lips but are being bred for darker lips.
Russelliana or Suave has a pale pink lip, paler than Carnea.
Roxo-bispo occurs only in Santa Catarina state. It has pure white tepals, and a pink-purple lip the color of a Roman Catholic bishop’s ceremonial robes.
Vinicolor or bordeaux is a red wine color. This is a very rare color, so flower form is not as important when judging.
Rubra has strongly-colored petals and sepals, and a red lip.
Sanguinea is a very dark red.
Anelata has a white lip with a narrow ring of color near the edge. The lip can have any color.
Argolao has a white lip with a ring of color up to 1/3 the lip width. The lip can have any color.
Marginata has a very dark rim on a white lip. The lip can have any color.
Oculata has a white patch at the tip of the lip, separating the color on the rim. If this white spot did not exist, it would be a Marginata. The lip can have any color.
Mandayana has no grooves in the jaws of color in the throat.
Flamea has patches, of any color, that radiate out along the petals and sepals, against a lighter background, looking like flames.
Striata has unbranched lines or stripes, of any color, that radiate out along the petals and sepals, against a lighter background.
Venosa is similar to Striata, except the stripes branch as they radiate outwards.
Werckhauserii striata is found in nature.
