Design

Generate split complementary color schemes with harmonious contrast using base color and two adjacent colors to complement

Design

Adjust color temperature by shifting colors between warm (red/yellow) and cool (blue) tones, perfect for mood lighting and atmospheric effects

Design

Generate tetradic color schemes with four colors arranged in rectangular patterns on the color wheel, creating rich and complex color relationships

Design

Generate lighter variations of a color by adding white, creating bright and airy tints for fresh design aesthetics

Design

Generate triadic color schemes with three equidistant colors on the color wheel, creating vibrant and balanced color combinations

Text Processing

Convert between letters and numbers (A=1, B=2, … Z=26) with configurable separator and case, decode numbers back to letters, and compute the letter sum of any text.

A guided 5-column CBT thought record that detects 10 common cognitive distortions and helps reframe automatic thoughts into balanced alternatives.

Health

Calculate the alveolar-arterial O₂ gradient to distinguish hypoxemia causes. PAO₂ = FiO₂×(P_atm−47) − PaCO₂/0.8; A-a = PAO₂ − PaO₂. Normal ≈ (Age+10)/4. Elevated → V/Q mismatch, shunt, diffusion impairment. Derived from StatPearls, LITFL, Cornell PICU, and Martin 1999. Not medical advice.

Health

Calculate the Absolute Neutrophil Count (ANC) = WBC × (segmented % + band %) / 100. Unit selectable: cells/µL or ×10⁹/L (1 ×10⁹/L = 1000 cells/µL). Adult reference ≥ 1500 cells/µL. Neutropenia risk strata: mild 1000–1500, moderate 500–1000, severe < 500 (agranulocytosis < 200) — high risk of serious infection, and febrile neutropenia is a medical emergency. Clinical uses: chemotherapy cycles typically require ANC ≥ 1500 to proceed and ≥ 500 for discharge from protective isolation; carbimazole/clozapine monitoring; congenital neutropenia workup. Neutrophilia > 7500 suggests bacterial infection, inflammation, steroids, or a myeloproliferative neoplasm. If only segmented % is reported, set band % to 0; if the instrument reports an absolute neutrophil count directly (NE#), this tool is not needed. Based on ASCO/IDSA neutropenia guidance, Boxer ASH 2012, and MDCalc. Not medical advice.
