RGB to HEX

Léiríonn RGB agus HEX an fhaisnéis dhath chéanna ach i bhformáidí difriúla. Úsáideann RGB trí uimhir dheachúlacha (0-255) do chomhpháirteanna dearga, glasa agus gorma. Úsáideann HEX teaghrán heicsidheachúlach sé charachtar ina seasann gach péire do na comhpháirteanna céanna i mbonn-16 (00-FF). Táirgeann siad dathanna comhionanna nuair a dhéantar iad a rindreáil i gceart.

HEX is commonly used in CSS and HTML for its compact format and widespread browser support. RGB is useful when you need to dynamically adjust color values with JavaScript, or when working with opacity using the rgba() format. Many developers prefer HEX for static colors and RGB/RGBA for dynamic or semi-transparent colors.

3-character HEX codes are shorthand for 6-character codes where each pair of characters is identical. For example, #F00 is equivalent to #FF0000, and #123 is equivalent to #112233. This shorthand works when both characters in each RGB pair are the same, reducing the code length while maintaining the same color value.

HEX codes can represent the same 16,777,216 colors as 8-bit RGB values (256 × 256 × 256). However, HEX doesn't natively support alpha (transparency) channels, unlike the rgba() format. For transparent colors, you would need to use RGBA or the 8-character HEX format with alpha (#RRGGBBAA) which is supported in modern browsers.

Úsáideann an tiontaire seo comhshó matamaiticiúil beacht idir luachanna RGB deachúlacha agus ionadaíocht heicsidheachúlach, rud a chinntíonn cruinneas 100% don spás datha RGB 8-giotán (luachanna 0-255). Is comhshó cinntitheach é, rud a chiallaíonn go dtáirgfidh an t-ionchur RGB céanna an t-aschur heicsidheachúlach céanna i gcónaí, ag teacht le caighdeáin tionscail a úsáidtear i mbrabhsálaithe gréasáin agus i mbogearraí dearaidh.
