Ratta1 [pp. of rañjati, cp. Sk. rakta] 1. dyed, coloured M i.36 (dūratta -- vaṇṇa difficult to dye or badly dyed; MA 167 reads duratta and expls as durañjita -- vaṇṇa; opp. suratta ibid.); Sn 287 (nānā -- rattehi vatthehi); Vism 415 (˚vattha -- nivattha, as sign of mourning); DhA iv.226 (˚vattha). -- 2. red. This is used of a high red colour, more like crimson. Sometimes it comes near a meaning like "shiny, shining, glittering" (as in ratta -- suvaṇṇa the glittering gold), cp. etym. & meaning of rajati and rajana. It may also be taken as "bleached" in ratta -- kambala. In ratta -- phalika (crystal) it approaches the meaning of "white," as also in expln of puṇḍarīka at J v.216 with ratta -- paduma "white lotus." -- It is most commonly found in foll. combns at foll. passages: Miln 191 (˚lohita -- candana); Vism 172 (˚kambala), 174 (˚koraṇḍaka), 191 (˚paṭākā); J i.394 (pavāla -- ratta -- kambala); iii.30 (˚puppha -- dāma); v.37 (˚sālivana), 216 (˚paduma); 372 (˚suvaṇṇa); DhA i.393 (id.), 248 (˚kambala); iv.189 (˚candanarukkha red -- sandal tree); SnA 125 (where paduma is given as "ratta -- set' ādivasena"); VvA 4 (˚dupaṭṭa), 65 (˚suvaṇṇa), 177 (˚phalika); PvA 4 (˚virala -- mālā; garland of red flowers for the convict to be executed, cp. Fick, Sociale Gliederung 104), 157 (˚paduma), 191 (˚sāli); Mhvs 30, 36 (˚kambala); 36, 82 (rattāni akkhīni bloodshot eyes). With the latter cp. cpd. rattakkha "with red eyes" (fr. crying) at PvA 39 (v. l. BB.), and Np. rattakkhin "Red -- eye" (Ep. of a Yakkha). <-> 3. (fig.) excited, infatuated, impassioned S iv.339; Sn 795 (virāga˚); It 92 (maccā rattā); Miln 220. Also in combn ratta duṭṭha mūḷha: see Nd2 s. v. chanda; cp. bhava -- rāga -- ratta.
